There will be also tubes for MM and MC phono stages (4 on top, 2 underneath)

Phono input will be switchable between MM and MC. For MC will be used input transformers and 6S17K-V input tubes.

I'd say it is a very safe bet that you are pleased with the sound and performance of this amplifier. I hope to get started on my own design in the near future, looking forward to getting it done - first though I have to finish the GM70 amps..

I am working in parallel on 2x200W tube amp using GU-50 tubes.

B+ will be 1 KV well regulated.

I was fantasizing about the same 4gu50 tube PP. Although a 2 tube PP would look better I guess and 100W is only 3 db less than 200W.

Mine will be 250W limited by an optical peak compressor on 200w.
