829 or GU-29 audio amplifier schematics?

AcidEye · 2nd February 2007, 02:13 PM

I'm looking for audio amplifier schematics using 829 or GU-29 tubes. After searching this forum, no schematics of my "taste" could be found for these tubes... The following interesting schematic was found for the little brother of the 829, the 832:

Does anyone have a comparable schematic for an amplifier with the 829 or GU-29 tube (more output than 832)? SE schematics are also welcome!

Kr,

Martin

Thanx!

These schematics are new for me, maybe I should start searching with Russian characters :-)

Today, I've located the sockets for these tubes at an affordable price, it will take some time before I've located all parts for a complete amp.

You might want to take a look at

coldwar.

You will find a lot of usefull info there.
I build this fine sounding amp some years ago.

For those who are interested in amplifiers with these kind of tubes, I've found a nice project with a tube comparable to the 829 on Jogis page:

http://www.jogis-roehrenbude.de/Lese...29-SE/3E29.htm

For this SE amplifier, the JAN 3E29 tube is used (which is mentioned to be similar to the 829).

This is a nice 829B amp.

Saw this thread on friday and thought for myself, this I must try

I built a prototype today and I find it quite interresting I must say, the first thing I notised was that the amp is completely noiseless.

When I started the first channel to test it I thought it didnt work, there was no hum or fiss in my speaker. Then I turned the sinusgenerator on and sure, there was sound

I havent meassured dist and outputpower yet but there is potensial in this tube, I will build one in a real chassi, thats for sure

Got a bad pic from the prototype, I got no real camera so no closeups

Hi Adalin,

The results from your prototype sound very promising!

Did you use the 829/GU-29 or the 832/GU-32 tube for this setup? What schematic and operating voltage are you using?

Please keep us informed on your project and findings, I like the concept of using unusual tubes for audio applications :-)

Kind regards,

Martin
