Disconnecting two power valves. Will this work?

[Masco]

Phil, I´m trying to get power amp distortion at lower volumes. I have a VVR installed, I thought this could be a complement to that. No single solution will get me significant reduction in volume, maybe both will get me closer to bedroom power amp distortion, so to speak. The VVR alone I can reduce to 30% voltage before it starts to sound awful.

What kind of master volume are you using?

This.

Sounds like you're slamming the output tubes w/ too much signal. Try a "bootstrap" style MV at the PI or some other means of attenuation before output tubes.

Also, what is the VVR scaling?

I suppose you could use 2 OTs, one for each pair, each driving a separate speaker to avoid the mismatch.
