Pyramid-V prototype. 2x80W nominal, Russian military tubes. MOSFET voltage regulators for filaments, screen grids, pre amp. This is a concert version, with grill top and TRS ins/outs. 0 dB input, outputs: 4, 8, 16 Ohm. Transformers custom made by EDCOR USA for 20 Hz - 20 kHz on full power.
Studio monitor version has a rack mount face plate; home stereo version has banana and RCA sockets.

The switch is for safety purposes.

A serious bit of kit then by the sound of it. Very nice job indeed.

Thanks Karl!
It sounds really nice as well; now it works in my living room playing music through phased arrays made for concerts. I forgot to mention, it has a proprietary anti-clipping network with optical compressors. Ever clean sound.

Looks very nice and retro.

Retro?
Ergonomically designed things are modern forever.

Hi edfed!
Nice work!

Can you tell something more about your amplifier?

Seeing the IC on input i guess that amplifier works on 2x15V, so it can give 18w per channel
