Nick update

Nick ,his up date on 7th May 2022 Tacoma.WA USA

Comment from Mr Nick on 14th June 2022 in Tacoma WA USA he said
The amp is very good and I listen to it often. 
It compares very well to all of my amplifiers and sounds very powerful - more powerful than the Pass Sit3 (17 watts)  and just as powerful as Herron MA1 monoblocks (100 watts) 

Mr Nick, thank you so much for your small comment
There was a throne. Your detailed words
It is a bigger rating than the comment on one page.
Sincerely thank.

About me

I am a garage maker that sells vacuum tube amplifiers and small audio equipment that I have made as an extension of my hobbies in one room of my apartment.
There are many people like me in the world.
We call it a one-man factory. In my case, the audio transformer uses a genuine transformer manufacturer's transformer made in Japan. For the power transformer,
we order a transformer that matches the voltage of the country you ordered from General Transformer Sales Co., Ltd., which has a store in Tokyo, and have them manufacture a special power transformer.
Personally, I worked for Panasonic in Japan for a long time, working in the audio field as an employee. Currently,
I am in charge of repairing a sound rental equipment company for elderly people.
There was a time when I worked overseas for more than 10 years as an expatriate for a certain audio manufacturer. Having those experiences is all around me.


2A3/45 Single Ended Amplifier Eurpean version
The 2A3 single amps I made are often used in South America or Canada.
Most are 230V areas. The amplifier introduced here is also European Version

Note :

This site contains a site translated by Google, a site written in my immature English, and a Japanese page.
The hobby page has not been translated into English, and many people have pointed out that the English translation is not very good, but this site
We specialize in introducing tube amplifiers and other electronic equipment.
I think it would be good if we could get the information.
Thank you for your understanding. Kenji

Go to the vinil of world DIY RIAA


This RIAA using LCR, uploaded by Mr Victor Serrano in Germany and his amplifier is here can see

All of Amplifier are made by Mizushima Japan


USD $ 1600 dollars include shipping and valves,only RCA input MM.


Money transfer is 2 way .Bank transfer or PayPal.

Customers say that they have purchased quite a few RIAA equalizers in the last 20 years.
Some of them cost thousands of dollars, but I was interested in the RIAA that Mr Mizushima made because I had the opportunity to use it.
He said he had time to listen to the thousands of vinyl records again. He said that he was very satisfied with the reproduction sound that was close to the original sound.
I think you can understand it even on youtube.

I think that the sound of recent vinyl discs can be played with a RIAA equalizer manufactured and sold by any major audio manufacturer and feel that the sound is thin.
I think that this LCR type equalizer can give you a relaxed and comfortable sound that you can feel when you listen to it.
You can make your own, but I don't think $1600 is an expensive price.
Mr Victor Serrano says that the sound is highly praised. In his case, it was a prototype, so it cost US$3,000, but he said that there would be people who would buy it for US$5,000.
Only this time, I am thinking of making and selling it for $1600 US dollars only for customers in the USA. We do not have stock, so it will take about 3 months.
Customers are limited to USA. One reason is that due to covid19, EMS distribution is only enabled in the United States.

The best sounding phono equalizer in the world at a low price. A very good sounding equalizer preamp that few people have experienced. make a sound
I'm sure you'll be impressed. This is an equalizer preamp designed in line with the RIAA.
The Recording Industry Association of America (RIAA) is the trade association of the recording industry in the United States.
Many record labels and distributors are members, and it accounts for 85% of the total distribution volume in the United States

Note:The price Mr Victor said was $10,000. He said even $10,000 is a cheap price.
Prices only for Covid 19 time. It is unknown how long this price can be maintained.
You probably have a lot of vinyl.
I think that this low-priced RIAA amplifier is a very cheap purchase when I think that I can draw out sounds that I could not make in the past by using this RIAA.
The end of the century RIAA amplifier came out. It came out of Mizushima's hand.

There are non-displayed products in Japanese products, and there are many made in Japan that show no intention despite reign as a famous manufacturer.
The amplifier I made is a product made in Japan. It is a true Japanese product. Of course, some parts are imported from China or parts manufactured in USA.
That's because Japan has already become a country that can not make parts. However,
important parts are selected from the good tests from the parts manufactured in Japan. Transformers
Capacitors, switches, screws, chassis, resistors, etc. I use them.
The product I thought and built up with Japanese thinking is my product made in Japan.

Various living environments and lives have gone crazy with convid 19.
Successful development will be after 2023. However, I am doing minor updates. Thank you for visiting this site.

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 $ 3500 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.
