"My initial impression is that the low gain amp is fairly loud at 12:00. You can push it to 1 to 1:30, and it still sound good. At 2:00 it goes into distortion. If you permit me a colloquial term, compressed. And not that loud either.
With a 12AT7 your ears would bleed before you ever heard any distortion or compression."
Then there's something wrong with the operating point of the low gain driver tube while the 12at7 is running properly.
With your speakers you should need much power at all and a low gain driver tube should give you plenty of system gain without distorting.
Can you give me details of each driver stage?
