Wow beatiful finish and detailes on those cubic transformer covers on top. Faceplate does not impress me as much, but still nice looking.

In the Biz, certain tube types are known for there sound. Also one can know, by past experience what makes a good supply and drive tube and which ones make a good source tube. Also, from personal experience, they can know which combinations work well or marry together. Then again some of this can also be born out by doing the associated amp construction math, finding that a given drive tube will have to be pushed to hard with higher plate voltages to have enough umph to drive a certain supply tube thus causing and increased chance of creating distortion in the supply tube or even premature failure, just as one example.
Uh, yes, thanks. Not at all what I was asking though. I was trying to figure out how that guy came to the conclusion he did regarding the amp's aesthetics and sound without knowing anything about it. He answered the question for me a few posts later (he didn't even realize it was an integrated amp).
