WE 300B Single Ended Amplifier with James Transformer
Schematic is next, very clear sound and more powerfull sound I am getting.
casuse of 3 Stages Amplifier.from low frequency to high response are so nice.
I am using FE86 philips old type of FE86 with mesh plate for input line.
in generaly I am using for Main Amplifier at home from 2004.2 stage of 300B SE
with SRPP drive is a little bit difficult push low efficiency speaker like a my
System NS 300(90db/m/w).but this type of 3 stage amplifier is easy to push
low range.I like 300B with James JS-6123HS. Built up early 2004.
Actually ,,still using this 300B Single Ended Amplifier ,,EF83 + 6N1P + 300B EH ..enough ..good bass and mid and high is very clear.
and position of load impedance is 2.5K and I connected 6 ohms speaker 91dB/m/w so equivalent load impedance is around 2.7K ohms.
plate voltages 420V respecto with ground. coupling capacitor are Del Ritmo Vita Q ,low cost capacitor but getting sound very natural.
Max Power is 8 W rms.nominal power is around 7 W rms. much better than 2A3 but I like 2A3 sound from medium Efficiency speaker system.
Note: Single-ended amplifiers have low output power and require high efficiency speakers.
The efficiency must be at least 91dB/m/w. A full range of 96dB/m/w or better is good.
Some people use a horn type speaker with 100 dB/m/w. Choose high efficiency speakers instead of expensive ones.
please comparare with some Tango Transformer,James Transformer is narrow BW
tranformer terminal are assigned counter clockwise.so easily find which is primary and secondary.
Why Japanese Transformer are good !!!! much wide than any transoformer :FE12 Tango
This is H20-3.5U semi universal audio transformer USD $ 600 dollars pair
James's band width is not wide range, please compare with ISO Tango Transformers.
price is almost same as XE20S but technology does not reach level of ISO Tango Transformers.
if would like to buy James Transformer please see Tango XE-20S and Hashimoto Transformers,
much better for use single ended Amplifier.even FE-12S ISO Tango is good transformer.
often using Touei Transformer for Test and Kasuga Transformer too and budget transformer.
charactor are not so bad,both are small transformer maker.but get good quiality product.
one thing only making small power transformer.
this time a little bit change few things then changed upgrade sound getting with JS-6123HS.
choose 2.5K ohm impedance much better than before.not so bad sound getting from 300B SE.
Recommended Audio Transformer for 300B Single Ended Amplifier:
ISO Tango :FC-30-3.5S,XE-20S,U-808,FE12S,S-2595(40W 2.7K),S-2197(20W 1.5K)=FE-20-1.5S）,(Tango are change impedance
secondary tap for universal transformer.a couple years ago quite.but 2016 started again.
Tamura : F-2007,F-5002,F-7002,are almost max 8W and high price.F-5002 is good.
Recently Tamura has new line fpr Single ended amplifier.each one 's weight is 5 Kg.very heavy.
: F913、F912 and F915 are new .very reasonable price but max power is only 8 W.
Hashimoto : H-30-3.5S,H-20-3.5U(2.5K/3.5K 20W)(Hashimoto's transformer are change impedance at primary)
Noguchi Transformer.Noguchi does not have factory but big company made for Noguchi.PFM-15WS (15W)is good.
very nice transformer for single ended amplifier.
WE300B Single Ended Spec table
EH 300B SE and 24 bit DAC on 1st Mar 2012
Then next circuit is version up circuit on Jan 2012
first stage is ECC82(Ecc802S),12AU7 and 2nd stage es 6N1P or ECC88 then 300B.
much better sound getting from 300B. future I would like to replace other MFG Audio Transformer.
I did small up date of my old 300B single ended Amplifier.
frequency response is 20Hz to 75Khz at -1dB non NFB and 20Hz to 85Khz at -1dB with 5dB NFB.
sound is not so bad than before,more clear and good frequency response which using 2.5K .
Power is 7 W rms. must be use fix bias for more power.but 300B tubes are expensive so
does not need much voltages and power for one's pocket money.that's enough.
some day I will try fixed bias for this 300B single ended amplifier.
coupling capacitor are using Tone Factory Vita Q paper oil capacitor.
sound is very good clear tone from Tone Factory Vita Q.I recommended to use single ended amplifier.
this amplifier using KOA resistance.will be replace AMRS resistace at all.
resistance AMRS are good and good C/P has.just quater of price of AMRG but sound are very good.
there are carbon corted resistance.AMRG is also carbon and surface around tube of alminum then
corted by carbon painted. sound is very good low to high range.AMRG is about USD $ 3.0 dollars
in Japan slightly expensive resistor.AMRS is USD $0.6 dollars in Japan.
economy but sound is just same as AMRG.what kind of resistance is good ? Skelton and
Z201 Vishay resistance are very high cost but very good.
all signal resistor are replaced with AMRS and some parts is AMRG.
so what is matter with this amplifier sound ? very clear sound and female voice is
more feminin like and Pianos touch is very real now.this is carbon resistance sound.
But does not get low ranges, this is world of audio.sound is very clear but does not get low.
I will be back to Matal corting film resistance by Takman Electronics co Japan.
Takman Matal film Resistance(REY) by Takman and web site is Takman Electronics Co Japan show above picture is Takman resistance, very budget resistance but sound is best for me.
to get much low range and mid /high is so sweet sound.REX and REY are for Audio 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.
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

How to get high voltage from low voltage for 300B single amplifier B+
Recently many Diyer using this kind of circuit .for getting high voltages from low voltages wind of transformer.
just circuit so if try to test this circuit please test cut and try.will be get high voltages easily.
One of hint for 2A3 and 300B compatible Single Ended Amplifier DIY
About circuit diagram ,,show next
2A3 and 300B Compatible Single Ended Amplifier circuit
Note: I am using EH 300B in general.some time using WE300B and 300B Cetron when some visitor came to house. always using EH 300B. impedance is 2.5 Kohms.
3.5K is very histeric sound of girls .so 2.5 K is much better than 3.5K when connected 6 OHM speaker system.sound is soft and much bass before.
many person said Sheungwan 300B-98 is best. so I have some money I will get one pair of 300B-98.
other one is ,,Akihabara in Tokyo best sold 300B is 300B JJ .many audiophile said same words. 300B JJ is good sound stage.
without expensive 300B tubes.
and Keiko(NGG) 300B is good.how about ? and what do you think ?
Plays Jazz by Raspberry Pi B+ I2S PCM5102A DAC on 1st June 2015

My amp production is a product that is produced by prepaying Audiophiles all over the world. We are making and testing with all your heart
Such an amplifier can not be manufactured only by my income. It is a garage maker established by the act of the production client. Please understand it enough
The price of the amplifier costs at least USD $ 3000 dollars. This includes amplifier parts, hassle, and shipping costs is never a profitable job
80% or more is parts cost and use very expensive Japanese parts. The quality of parts made in Japan has fallen and not necessarily made in Japan.

PSVANE 300B with James Transformer 300B Single Ended Amplifier on Feb 2016
If would like to build up one of 300B Single Ended Amplifier ,very much stable on May 2016
Note: Driver used be use 6DJ8 family but much better use 6CG7/6FQ7 and 6N6P .6N6P is same of Sovtek 6H6N 4.8W dissipation of plate
please adj resistance .12K ~15K .but must at leaset need B+ 420 V.top of plate is 430V ~ 450V respect with ground.
2dry of Power Transformer need at least 360V( recommend to use 380V ~ 400V ) and until ~ 400 V.if you think high getting replace first capacitor of filter to minor value.
if would like to use with James transformer ,nothing problem to use.this circuit.Hashimoto H20-3.5U is very wide frequency response
from 20 Hz to 120 Khz at -6dB NFB. and Non NFB is 20Hz to 90 Khz frequecy response ,just like XE-20S of Tango.
if would like to use PT-220V or PT-220P even PT-220 .please ask dealer of Hashimoto about change spec of transformer.which are replace 0-4-5 3A to 0-4-6.3 V x2 wound.
there are very important ,because 5V AC can not make 5 V DC .4.8V if use shottky diode probably get 6.0 V so it enough to use 300B Single Ended Amplifier.
if use shottky diode will be get around 6 V DC then adjust some sires resistor for adjust voltage of filaments.
PT-220 Hashimoto can not use for 300B Single Ended Amplifier.if would like to buy one of Hashimoto,much better use local transformer at your local.
many small shop can make these kind of transformer for power supply.for ex some motor company, repair shop for motor.small taller repair's motor.
be careful ..... PT-220 Hashimoto can not use any Single Ended Amplifier for Direct heating Single Ended Amplifier which is using DC filament.
Hahimoto does not have any product of Power Transformer for direct heating DC .even Tamura , Noguchi(no own factory,only name).
so have to order to small company. one thing very important ,do not buy PT-220 Hashimoto if would like to get good 300B Single Ended Amplifier.

because good.more than 10 years using this one.
Just before Burn in 300B Single Ended Amplifier on 26th Nov 2016
300B Single Ended Amplifier on APR 2019 Name is KANADE
300B is very good valve,even China product QC is going up and PSVANE 300B 's sound is very close to WE300B made in USA.
and getting enough power at home.personally I like 2A3 Single Ended Amplifier with good audio transformer,but sometime
not enough power to get.first amplifier for one is EL84/6BQ5 Single Ended Amplifier.2nd Amplifier is 2A3 SET.then 300B SET.
these line are very useful at small room.

XE20S ( Hirata ) using 300B Single Ended Amplifier on Nov 2017
Schematic Diagram is here ,, EF86 is very difficult to get country side so choose ECC802 in parallel
If going up voltage of B+ ,can be use 10uF 630V at first capacity of power supply after 5U4.will be get B+ 435 V .this transformer capacity is
400V x 2 and 280 mA.so if your amplifier 350V x 2 AC ,can be use 10uF 630V for going up B+ around 400 V.a little more power than 47uF 500V.
10uF 630V film capacitor for first cap for power supply
This Encore 300B Single Ended Amplifier ,replaced 5814A Sylvania instead of ECC802.very clear and getting tight bass than 12AU7 family.5814A is
one of family of ECC82/12AU7 but different rate of them .sound is very stable and thinking good for Jazz. Piano solo.Sylvania 5814A is good.

It is based on the result of voting by 30 Audiophiles some day in Tokyo , it seems that it was "blind test" to exclude prejudice, so let's make a great deal of mind.
so most low price of PSVANE 300B is best to get good sound.I prefer too. actually I am using PSVANE 300B.sound is very good and enough to use my room.
and very much enjoy listen Music every day. very cheapest PSVANE 300B is best price and best sound.
WE 300 B is not necessarily good in the world.
I also feel that the sound is also clear and if used it sounds better. PSVANE 300B is a very good reasonable vacuum tube.
The LM78T05 5V 3A IC has been discontinued
I realized that I hadn't bought the LM78T05, but I thought it would be somewhere. I understood that I was not in Japan and I was asked by an IC importer.
If you check the distribution route, it turns out that there is no, compatible IC is called LT323AT. To be precise, it is a regulator of the LT323AT LDO. It is around 700 yen for 1 piece.
There was other compatibility. MIC29300-5.0WT ◆ The name is 3A, 5V. Therefore, two kinds were hit. I ordered several pieces because each store seems to have stock.
The first 300 B single amp in 2019
The power transformer has been made one rank higher. As you can see from the circuit diagram, it is 430 V even if the B + voltage is loaded. That would have increased the plate current.
The low range has improved considerably. I also feel the same feeling of power, I can create an unmistakable sound either listening to Jazz or listening to an orchestra.
The power supply transformer is a special-purpose transformer for general transformers and sales stocks. The price was also reasonable. I have not measured it, but I think it is within the rating. Various until it produces a result
I tried a transformer. It is change of the existing transformer and the power supply capacitor. The rectifier is 5U4. I was asked to wind 5V 4A from the request to use this vacuum tube overwhelmingly.
I do not understand only the sound of youtube below, but I feel that it is clearly improved when listening to modern music etc.

Hirata Tango XE20S made on 2018
by Encore Cetron 300B picture came from chile .14th Aug 2019
The sound of these classic 300B tubes, which are a copy of the Western Electric and made in the USA,
is very similar to the Western Electric 300B: medium-range, high-definition range, with a touch of sweetness that does not affect the naturalness of the sound .
The response of the low frequencies is of great presence, perhaps more pronounced than the Western Electic.
The average frequencies go on the air with the same fidelity of the recording: if the recording is bad the sound is horrible, but with high-resolution recordings or high-quality CDs the sound is sublime,
you can distinguish even the different timbres of different violins , and even the timbres of the different strings of the violin ... is the extreme high fidelity.
With these tubes and this amplifier you have to have the entire audio chain with the same high quality. And if the source is not up to the tube and amplifier better forget ...
It is a privilege to enjoy vintage audio jewelry like these Cetron 300B tubes.
It is difficult to imagine that the musicality of the 300B tubes of the Cetron and Western Electric brands can be overcome.

The Cocoliso 300B has changed owners twice a times and eventually to Mr Pablo Prado of Chicureo, Chile, and about three weeks ago I received an email and asked for a picture
I received the image via email on November 30, 2020, and here it is. The speakers are made in Italy by Diapason Adamantes.he listened to them before using them.
First of all, I'm very happy with them. I'm sure you will take good care of it.
Nobsound mono 300B Single Ended Amplifier USD $ 1000 dollars
Recently I am doing repair Nobsound amplifier's for part time.this amplifier came from them Nobsound Japan for repair.just introduce you inside of amplifier.
quite good .circuit is same as sun audio circuit and triode.com audio amplifier 's circuit. looks very good ,inside is not so bad too, just show you inside.
then what do you think ? USD $ 1000 dollars may be out of Japan 's cost is a little bit high cost because shipping cost is not same.well I love these amplifier.
cocoliso 300B Single Ended Amplifier in Chile Dic 2020
Nobsound power supply circuit not an ordinary circuit
This circuit uses a diode bridge, which is very common these days. The rectifier tube is not used as a rectifier tube, it is just used as a damper for the voltage drop of about 60V. The rectifier tube is not used as a rectifier tube.
If you look at Amazon's website, you will see that the PSVANE factory in Shenzhen burned down last year in 2020, and they were unable to get good vacuum tubes, so they made this circuit as a result.
But the rectifier tube does not play the role of rectifier in this circuit.If use normal circuit and normal Japanese transformr will be come good amplifier.these thing is problem of Made in Chaina.
It's a shame, but I think it's a good amp for educational purposes.
