I said it over on your other thread, but I guess I'll say it again. The issue you'll have with your amp idea is that it's not just a matter of cutting power. You are asking for at the very least two power sections, and quite possibly two preamp sections as well. It's not impossible, but you're basically cramming two amps into one chassis. Doesn't sound like a good idea to me.

If you want to cut power at the end, that can be done, but that gets back into attenuator or power scaling land, which it sounds like is not what you want.

There are lots of amps out there these days that offer power cuts. I don't know of anything Tweedish, but I've yet to find any that I find remotely satisfying. Doesn't mean they're not there. I just haven't found one. Granted, I stopped looking, as I decided it was silly to ask an amp to do too much...
