Hi,

Good for you that you found the problem.
A few questions, not relating to your particular problem but to the construction of the amp.
How does it sound?
The 6T10 compactron is a strange beast. The output pentode-section does what it's suppose to but the other section is ...well, strange.
The weirdest plate-curves, absolutely non-audio imo.
Now, could this problem be solved by biasing grid-3 as with D6,7,9,10?
Will this square the curves up to something usefull?
Anyone has an idea? Or even better, does anyone have curves with this biasing?

rgds,

/tri-comp

the amp actually sounds good to me but is only the second tube amp I have built.
as for the more technical questions I don't have an O-scope.
Pmillett could answer any questions you might have as this amp is his design.

Pete Millett's DIY Audio pages look for mighty midget.
