slightly offtopic
Hi,
offtopic but I did not want to start a new thread.
Please find attached famous transtube circuit. Peavey claim that this topology gives good sound.
I simulated it and looked for soft clipping like in tubes, but does not! Even not hard overdrive gives sharp waves.
Could enyone explain why Peavey used this solution?
What is a benefit to collect a signal from both collectors?
Do transtube versions sound better than with only opamps?
regards
P

There is a LOT more to a tube sound than just how it clips.
The transistors are wired together at their collectors as a Darlington pair. Look that up. The point in the Peavey circuits is that it tries to make the stage act more as a voltage amp than a current amp. That is said to more resemble a tube stage.

Welcome to the forum, pad. I don't know why you wouldn;t start a new thread, they don;t cost anything. And that way you would get better response than tacking on the end of a 2006 thread. Likewise linking from the end of a 2004 thread is not the best way to get noticed.
