Hi Kevin,
Maybe I wasn't clear enough about what I meant. On this particular amp I found I had a harder time dialing in the power scaling compared to the amp I made for myself in reference to when it was full on vs having it off (I added a switch to be able to turn it off). This particular amp was similar to a Deluxe Reverb but with 6L6GC tubes and a lower voltage than I would have liked. It would sound a bit too fizzy when the power was down and master volume and volume controls were adjusted to try to emulate all the way up with power scaling off tone. I could have got it dialed in eventually but the customer wanted the amp quicker, and he eventually had me take power scaling off it entirely because he wanted bias modulating trem and I had trouble getting that to work with power scaling installed. I'm sure that could be done too, but it would have to be scaled on it's own in reference to the main power scaling. He supplied me with the parts for this amp, so I was locked into certain choices. He had some other guy building it originally but that guy took too long so he came to me, and I redesigned some things and started off with a fresh cosmetic design and circuit design, but using his transformers and chassis.
The other amp I made for myself with power scaling incorporated was 50-55 watts and made out of a Bogen transformer set and tubes and then I added my own circuit and changed a couple tube types, etc. Maybe the higher headroom amp is a little easier to dial in.
