Nice room nice gears nice people.

The sound diffuser seems particularly well made. Congratulations to place tubes and vinyl with the right speakers. The smiles and relaxed atmosphere speaks for themselves about the great quality of the event.

people in the picture had a thing or two to do with the exhibit,
i made the tube power amp, another made the preamp, another one made the speakers, and still another made the linear tracker tone arm....
it was a group effort....

people leaving the room had big smiles...they liked what they heard...
next year another set-up....i am planning to make a Kimmel OTL...

Amplifier is designed so that you can choose different output tubes. ГМ70, ГК71, 813, ГУ13 and other.

I have GK-71's, can you share your schematics? might consider building it.
Thanks

I have build an 813 PP amplifier four years ago. I have to build the 2nd channel yet but I need to find two 500W output transformers. The one I used gave poor results.

It is waste of ГК-71 using it in a triode connection. Pentode A2 with local feedback around is what makes it The Queen!

I use SMPS for filaments of such tubes. Amps are much lighter and compact.

I also use SMPS for the filaments in my GM70 stereo SE A2 amp. If I didn't it would have been a two chassis job and wasted even more power as heat. So not only efficiency but space can be saved using switchers.

Good work Wavebourn.

Cheers
Matt

Thanks for the tip, actually they are intended for PP monoblock but I'm still looking for a good schema to base on. I already have the OPT and Power Trafo with 1kv B+.
