built up KT 88 single
ended amplifier on 24th May 2004 this time useTango MX-205 power transfomer.max rate is 210mA current capacity.and plate voltage are 320V.cathode resitance are 272ohms. 272 ohm slightly higher than normal.i selected this value for compatibilty
of EL 34.so you never use EL 34 ,should be 150 ohm for cathode
resistance for
6550 and KT 88
better.

I got around 25V so current are some 90mA include G2 current. I never know 6550 and KT 88 are different charactor.sound like EL 34 but 6550 is just like a 6L6GC but more potencial. KT 88 's high frequency response are very nice and sound like a EL 34 .this time I took off 500K 18K and 0.1uF networks.and does not have over all NFB.only use UL connection.UL is some kind of NFB as you know about it. around -3dB NFB ,could be get on final stage.but slightly bright sound I got.so heve to give some over all negative feedback around from 3 - 6 dB for good
DF(3).Rf is
2.6K .OUT PUT Transformer are small economy transformer.

SRPP : 500K , 18K and 0.1uF network(u(mew)Drive is not necesary if you can get suffucient power from power tubes.so you can take off these components.Rf is need to adjust with AC dB meter respect with DF (damping factor ) of your speaker system..I guess 3 stages or 2stage p-k reguler amplifier are better for enough to get power.such as a triode -cathode follower and final stage is best choise of amplifier.and get powerful sound.even i got very powerfull sound. heater bias needed for SRPP stage for protect cathode of driver tubes . Choke coil is 5H 200mA .
Input capacitor are no exceed to 47uF 500V.so max is 47uF for 5U4G for protect 5U4G rectifier tube.more than 47uF get damege of rectifier tubes. please see 5U4G spec.
some bypass condensor are MUSE condenser and Black Gate.and coupling are film capacitor and Vita Q in parallel.Vita-Q get more natural sound. sience 8th Mar 2004 from Japan.K.M

How to calculate coupling capacitor for low frequency Amplification

Coupling capacitor value select ,depend on internal resistance of driver and load resistance and grid leak resistance value.
please see next Fig and off course Single Ended Amplifier bass is depend on large core of audio transformer. so small transformer does not get enough low.
these case is not only penthode ..even use same theory use for triode. triode low impedance tubes are much more reproduce low than penthode.

grid leak resistance of KT88 must be use around 220K ohms. and if use 2A3 triode use less than 500 K ohms.many case say 2A3 is around 200K ohm (130K)...
KT88 is around 150K ohms ...must to use.not reach to 220K .please see next text KT88

very important.value for "No Screw Up Tubes".for example RCA 50 is max 10K ohm.very low resistance.in general triode are very low.
cut off frequency of KT88 is around 1.6 Hz when use 0.47uF coupling capacitor and grid leak resistance choose 200K ohm. but depend on impedance of driver.
many case coupling capacitor choose around more than 0.47uF in that's case.easily to calculate roll off frequency ..please try it's.
when using fix bias for KT88 must be use 100K ohms grid resistace and fix bias of 2A3 use max 50K ohms.if your amplifier has good and large core of Transformer
please choose good value of coupling capacitor and grid leak resistance,,probably will be get good low frequency response .
if one amplifier need NFB must be calcurate reasonable staggered ratio.

This picture is EL34 and 6B4G (same like 2A3 but 6.3 filament direct heating valve)
on 26th Nov 2005
with switch +B 320V to +280V and filament voltege is trough rectifire bridge some condensor into filament or heater of EL34. same US Octal Base you can use both way indirect and direct heating tubes.
I got 4.5 W output when I used 6B4G Single Ended mode.sound like small 300B sound and very clear.felt
much power than EL34 SE .however half power of EL34 SE.

6B4G and EL 34 Compatible Amplifier ( 6B4G and EL34 are same US(octal)BASE used)

Circuit diagram is next.

How about will you replace resistance in your an Amplifier
Do you know ? material of resistor change sound ?
actually we can use 2 type of film resistance for Audio circuit recently.

(A) Carbon film resistance

AMRG

these are film carbon resistance
Charactor: sound is very clear low to high frequency and feel sound is clear and good
for pre-amplifier or flat amplifier.
famous resistance are "Allen & Bradley carbon solid resistance" "AMRG" "Rikenorm Riken RMG" "AMRS"
"Rikenorm Riken RMA" "Taiyo FTR" "Rikyu RD-25TJ" "Takman REX resistance" etc etc

(B) Metal film resistance

and this is Metal film resistance RSN1S TDO resistance

Charactor: Sound is good low ranges and good high range . if your amplifier does not get good low(Good Bass).
please try to replace of all resistance of Metal film resistance. You will be get good Bass and high frequency
tone. famous resistance are "KOA metal film MOS1/2C " "Vishay Metal film Z201" "Skelton Fukushima-Furaba"
"TDO, Solist or Takman Metal film" "Vishay MBB0207-50F" "AMRA" "Rikyu RO-25CFK"
"Vishay RN65D" "Takman RLF" "Tokyo Koon denpa RD" "Nikkohm solid resistance RP" "Alfa Electronics FLCX"
"Vishay VSR" "Takman REY" etc etc.

so recently I like sound of "Takman REY" and "Takman RSN1S" to get good bass from
my single ended Amplifiers.Nikkohm RP are good too.
REX and REY resistance Takman

Takman Resistance Co Japan

Nikkohm Matal Resistanceuse for High End Audio and RF

so Resistance change sound of your Amplifiers.
probably the carbon resitance are good for pre-amplifier and some parts in power supply circuit.
how about you ? please try to use different resistance into your amplifier D.I.Y

Another option is 300B Single Ended Amplifier

What is Bias ? for EL34

Bias is , if do you speak english ? automatically knows about what is bias.
bias is A divide by B , A is Ip current , B is Ep current.
some one said which is correct bias for EL34 etc. I said that correct bias voltage
does not have.so it's is depend on what kind of transformer do you have? and
what kind of connection do you would like to use and depend on what kind of power
suppuly use.if would like to use high voltage like a 420V. plate current should be
chooese low.and out put impedance is high.if would like to use UL or triode connection
bias is high voltage, low current and impedance is high like from 5K to 3.5K ohm.
if would like to use low voltage like a 250V. must be use high current for plate.
and depend on type of Amplification as A , AB1 etc. single-ended means Class A.some
time use class A+A2 etc.disspation EL34 is 25W so you have to use less than 25W .
caluculate Ep X Ip .ex) -26V Eb 350V Zp= 3.5K 26V X 1/√2= 26 X 0.707= 18.4 V rms
26/70mA = 370 ohm.if you are using auto bias. you are use 370 ohm.these value is
depend on 3.5K ohm line on Ep-Ip curve of EL34.70mA means, Max is 130mA needed
plate current.3.5K ohm is triode connection.in generally use 2.5K ohm for penthode.
which impedance you would like to use is first then I can know about bias, Ep and Ip.
easy to caluculate if you can get Ep - Ip curve for each tube.A1 triode is 370 ohm
for cathode.Ep is 375V.Rl is 3K, 250V ,-14V for Eg and cathode is 14/0.07 = 200 ohm.
same way if use 2K imp and -13.5 V for Eg then 13.5/0.1 = 135 ohm.
Bias for EL34 is depend on your mind.your favorite sound.in generally EL 34 plays
2.5K load and G1 Bias is around -13.5 to -14.5 V Ip is 80mA 175ohm for cathode.
when plate voltages is 250V.will be get sound like grave.and POWER is around 10W.but
10W rms with EL34 is critical.10W EL34 is depend on your Transformer.small one get
small power.disspation is 25W so if choose 100mA Ip and you must be use plate voltage
is less than 300V.must be use 250V for plate.and if would like to triode connection
Rk is 390 ohm and plate voltages are some 370V.automatically load impedance is 3.5Kohm.
sound is each other different."GB multiplication is always iqual(same)."

About coupling capacitor

, please choose proper value for cut off at low position frequency and in circuit you can see 0.33uF 630V of C and leak resistance of 300B is 100K to 300K R you can caluculate how fx= 1 / 2x3.14 x CR = 159 / C(uF)x R(K ohm) ex) fx= 159/ 0.33x 220 = 2.19 Hz.roll off frequency.so first you need look how much at least need 300B grid leak resistance and please caluculate proper value of C and R are very important.and SRPP gain is depend on from 1K ohm to 10K ohm to replace load resistance.sound is depend on you like which are choose coupling capacitor and leak resistance if you do you have some high value inductance some more than 400H .for grid choke when are you would like to use 300B , 6B4G etc.

Film Capacitor has direction

any film capacitor has direction .film cap made up inside to outside.inside of core
is "Output" and outside is "Input".next is indicated detail.
if one's use Arizona Capacitor ,,blue Cactus figure side is out side(end) of wound so input where connect high voltages.
other case is if use for bypass outside is ground.so blue Cactus side is ground. some case is different . please ask components mfg company
which is end of wound. must be ask to them for to get good sound.very important.

Arizona Cap Blue Cactus and Green Cactus(brand new 2014)

If do you would like study more something about an amplifier.
please see "Stagger Ratio"for An Amplifier design.
Not only 300B triode even penthode like KT88
have to adjust C(coupling) and R(leak resistanse)under SPEC of
TUBES.most important thing is" how is sound with your speaker system

and your room where you are always listen faber MUSIC."at least
you need know DF(Damping Factor)of Penthode is very low.like 0.5
but Triode (low mu like a 10 from 3)are around 2-3.Direct heating
Triode (45,2A3,50, 300B ,275,VT52 etc) are useble as a NON NFB
SE Amplifier.but Penthode are not.Penthode need NFB or 2nd Way.

"UL is kind of technic of NFB" and UL get around 6 from 3dB

of NFB into final tube and closely same effect of cathode negative

feed back at output tubes cathode.I always feel good -3dB with
many Valube Amplifier with high effiency speaker(over 90dB/m/w).

and always I asked many person how much did you get DF your

Amplifier D.I.Y? if some one said DF=1 . I said OK bad amplifier

did you built up.Power Amplifier are not power.Power amplifier has
Good DF.push pull get around DF=10 and SE get around 2-3.

An Amplifier SE D.I.Y has good DF at least 2-3.can move yor JBL and if
would like to use SRPP for Drive ,output impedance is very low but gain
is not enough for power tubes so you can caluculate gain for SRPP drive
to set up your power tubes ,please see for some idea more gain of SRPP click here .ex) ECC83 if use , cathode resistance are around 1k ohm to 2.5k generally
but some time need more output gain.please to try to use value of from 2.5K to 5K ohm.

Note: Russian 6550 and KT88 are almost same cahactor.I think same tube.
if driver can get max 40V rms , can be use any drive amplifier like P-G amplifier by 12AU7
ECC88 etc of one driver.KT88 sound is very similar of good triode amplifier.
but EL156,KT90,KT120 are almost same kind of sound.not get mid high is clear.
KT88 single ended amplifier is just like good triode amplifier sound and good bass.
charactor is just same sound of EL34 but more powerfull.off course depend on good
transformer use.transforemr is at least need 10(20Hz) to 100Khz(80Kz) bandwith.
10 W rms power so need more than 20W capability of power.so KT88 single ended Amplifier
very popular for Audiophiler.KT90 is not same family of sound of KT88.KT90 is
PL509(top plate) Sweep tubes modificated.sound is very tight and dry.for me
not recommended to use audio amplifier.EL156 China is not bad and easily to drive
any kind of drive amplifier ,just a half of 6DJ8,12AU7 enough to drive.
whay can I say,,,,KT88 is the king of valves.looks good ,sound good, easily to drive.
other way Triode Single Ended Amplifier get sound of other world of sound.

some one said,,, often get low edge oscilation around 50hz-100hz sometime 20-50hz... I think problem of phase .some circuit has NFB over all ,just like NFB from 2dary of audio transformer
to 1st stage of cathode hooku up some resistance with small capacitor in parallel .small capacitor is around 100pF to 300pF depend on low frequency boost.1/6.28*CR =frequency
almost 3 stages amplifier are input line and out line is same phase so have risk of osclation.if does not would like boost please take out small capacitor for protect low edges oscilation.
or change value of capacitor.just cut and try to choose value.and
if some time blow up fuse when turn on amplifier... because oscilation when unstable condition of power supply by turn on.
if using 2A fuse please use a little bit more like 2.5A or 3A fuse or slow blow.2A3 single...KT88 single using 3A anyway in my amplifier.///// I am so sorry bad english to wrote.please
understand ,,what is meanning. note:25th Nov 2013.. from Sakura Chiba Japan.

Not only power.

DF is very important and output impedance

explane for DF ,please move mouse on the Icon.

Fujii New Tech Amplifier for EL34/KT88 Single Ended Amplifier
Idea from most 2/3 multipul charactor amplifier and 3/2 multipul
charactor of Diode tube.good factor for Penthode SE Amplifier.
Mr Fujii said you can build up one of very low distortion
Penthode SE Amplifier like a push pull effect.what do you think?
Distortion is 1/20 time less than general penthode SE Amplifier.

KT88/6550 single ended cathode chork drive amplifier
what do you think ? cathode chork drive amplifier made up 30% more power than general g-k amplifier and I guess get some 3/2 multi curve and less distortion than general coupling amplifier. if you would like to use triode connection KT88 for final.may be get just like 300B sound from penthode.and limited cathode current amplifier made up very different sound.often LM317 for cathode of 300B and KT88 make diffrent sound amplifier.I guess ,,,,,6550/KT88 Triode connection sound better than 300B SE.???. ???.

Mr Durandal 2A3 Single Ended Amplifier from Germany

I think 2A3/45 SE Amplifier get best sound than 300B SE and KT88 SE
frequency reponse is from 10Hz to 35KHz -3dB by Noguchi PMF-7WS.
Max power is 4.5W rms under 2A3.

next I will be modificate above amplifier to WE 91B type
circuit diagram is next one and driver is EF86 UL connection type.

2A3 Single End Amplifier is better than 300B Single Ended Amplifier ???
driver using 5687 High current heater Miniture valve, double triode medium mew MU 16-18.
FE-12S is new 2008 model of ISO TANGO in Japan for SE Amplifier.max power is
12 W rms. recomend valve are 2A3, EL84, EL34 and 6L6GC etc.this is an universal transformer so
out put impedance are 2.5K, 3.5K, 5K and 7K ohm.frequency response is from 20Hz to
80Khz at 2.5K ohm and from 45Hz to 35Khz at 7Kohm, Max current is 60mA DC,1.6Kg each.

SRPP is very nice clear sound get for 2A3SE.but It's very difficult to get
enough gain when do you play classic.needed other low gain amplifier before SRPP
driver.I like sound of SRPP with ECC83.some one said 6N2P is good.
even 3 stages direct coupling driver with 6922/6DJ8 is good sound and enough to get
much gain when play Classic.Power is around 5W rms at 3% with Sovtek 2A3 and clear
sound.2A3 EH gold is a little bit expensive than 2A3 Sovtek and Sovtek 2A3 sound is much better
than 2A3EH gold.even 2A3C is good sound to get and very clear and powerful.

Driver ECC88 and 6N1P are more clear and not too much bass but sound more musical.
and I am thinking ,going build up next circuit is ...

Perque Drive for SRPP how to work?
I like 2A3 SE with SRPP drive. sound is very clear as you knew.
SRPP is good sound to get but low Gain and not enough to get sound when
listing all type Classic Music.however if use a u(mew)Drive SRPP to get
more gain than SRPP normal.1st time I used u(mew)Drive SRPP for 6550/KT88 SE.
u(mew) drive is a little bit more than gereral SRPP.some one said 29times.
SRPP general is 26 times.so u(mew)drive get a little bit more gain.this time I tryed
"Perque-drive" with triode and penthode combination valuve like a 6U8 and 6AN8.
result is very good and sound like SRPP and actually output sine wave is same
like SRPP output and much gain from Perque-Drive SRPP.
experiamented by Mr Tetsu Kimura and his nick
name is "Perque" (PERUKE). I don't know what meanning "Perque". so now I can drive
300B easy with SRPP.slightly need adjust value of cathode resistance of triode and penthode
for miner distortion or comfortable sound which do you favorit.
Perque-Drive is Next.

some mA.2SK30 is around 1mA to 5mA depend on Rank of 2SK30.safix is Rank.and easy to
make one limited current diode with one of resistanse within 1K ohm.

The people who made the amplifiers I made　Let's celebrate the brave amp builders!

My poor English is world-famous. It was about 20 years ago that a boy in Chicago asked me to teach him how to use a tube amplifier, and I taught him by email.
Frequently, the boy was saying that my level of English was low. and he did. At the age of 22 I moved to the USA and worked for a Jewish company for 3 years repairing amplifiers.
I moved to America at the age of 22 and worked for a Jewish company for 3 years repairing amplifiers. That is my biggest regret. I'm an old amp maker, over 70 years old. I will continue to make amplifiers, despite my poverty.
I can also speak Spanish, having lived in South America for nearly seven years, four as an expatriate for Pioneer. For the next three years I worked for the Motrola distributor in that country,
repairing Motrola radio equipment. My wife is a strong white Argentine woman. Her grandmother was English and her mother French. She has lived with me in Japan for 40 years and speaks Japanese more fluently than I do. Thank you for reading this far.
Thank you very much. I'll tell you more about myself when I get the chance.
Anyway, my English isn't very good, but it's all right if it makes sense. I'm sure there are foreigners who speak even worse English than I do. Please understand that this is not a site to evaluate my English. This text was written by translating my bad Japanese .

All Music Data saved in Music Server and getting Data from AT HOME LAN

in my house by small LAN and Music

Sound getting from LAN(home network) and CDP,DAT and LP player

Sound source are getting from DAT and DAC under DAT, CDplayer. 2A3 Single ended Amplifier has 24bit DAC inside of Amplifier . one of source came from LAN
File server using samba and test server. 4 PC connected each other by LAN. 2 of Server is using old PC low spec.file server using Samba and fireFly for mp3.
firefly can be connect any type of smart-phone.small system but enough to use at home.so I can replay FLAC ,wav any type of format(codec).
if do you have any old PC at corner of your room.please try to use as file server.It's very good idea.it is very economic and does not need to buy new NAS server.
OS are Linux, free OS.even if do you have modern type of PC ,you can use as Music Server lile Vortexbox and Voyage .etc Ubuntu Stereo too

If there is a pc that you no longer use the obsolete in a corner of your room, then this can be used
You can make a Music server. It is also relatively easy. It does not introduce in detail here, but please bestowed the life of a second old PC with your memories.

Vortexbox ,Voyage MPD, Ubuntu Studio ,Dephile, Audio Phile Linux and
Any Linux distribution but if use Linux and will be use IDE type old PC ,can be use until Fedora core 4,Centos 4 with old kernel Linux.
almost fabrication date is around from 2006 can be install Vortexbox, Voyage MPD and AP linux.if can not install Music Server please try old Linux version.
even you can use Volumio Linux for Music server.right now.instead of Raspberry Pi (Arm)

this amplifier EL34 and 6L6 special amplifier for those valves on 2022

I love EL34 sound

EL34 UL on 2nd Jan 2019

EL 34 is very nice valve as one of single-ended amplifier DIY.aound 7W get when use UL and one thing good is not expensive.you can use 90dB speaker's.

up load on 28th Mar 2018 as EL34 Single Ended Amplifier ,I think good for small room.

I set the amplifier using vacuum tubes of different types in the same circuit this time. I have to output tube famous 5998A as indirect heater triodes.
please see 5998A Single Ended Amplifier

His KT88 Single Ended Amplifier, 300B/2A3 Single Ended Amplifier D.I.Y some small detail D.I.Y
detail site.please see(visit.)
actually very much good.his amplifier and speaker system.DIY even he build up one of DAC external.

Very Important things for build up one of good an amplifier any amplifier,never use all of chassis for ground.
either Sony,Mark levinson,Jeff Rowrand many many Good Amplifier are using one point ground at back of chassis.almost close to input line

Company name is Hatt Audio Lab, very small company but they are making same line up of ISO Tango Transformers. character is much better than ISO Tango and
slightly low price from them.let's me show you PDF file PDF filefor catalog but in Japanese only.

this circuit is not original SRPP.we call it's "u(mew) follower for a little
more Gain than SRPP normal.
