you build one and I'll try it

one thing worried me, the use of the word efficient - don't they know how much guitarists love all the in-efficiencies and other sound de-grading "faults" of our valve amps?

Since, AFAIK there has never been a commercial guitar amp made with a regulated power supply (that BIG triode Will!)I submit that nobody knows if they would like one or not?

In anycase it is beer into water to "unregulate" a supply!

There is a bit of a ding-dong going on about this at musicradar.

The "real" vintage amps had valve rectifier circuits. When you played hard the voltage would drop (sag) and this gave a natural compression. I guess that makes unregulated supplies a desirable thing. Of course these old amps had none of the power of modern (1960's onwards) amps. I'm sure you know this anyway, just wondering out loud....

I have never played one of these old vintage amps either! I'm a bit like Percy in the 1st Blackadder - "I prefer the sound of something I've never heard, to the sound of something else, I've never heard....."
