SteveR	Re: And the man who pestered Steve speaks! I was just over at Randall's site and was thinking about your question. If you used a local NFB loop on one of the early stages (most likely first stage) wouldn't you get a limiting or compressing effect? It wouldn't behave like an active device but would limit the output swing so that you would have a more constant signal level, and you could drive the subsequent stages a bit harder. I think it would increase sustain without necessarily adding overdrive distortion. The triple giant preamp uses this in its clean circuit. BTW I've got a homebrew four 6V6 power amp that is SWEET. When clean it's deep and chimey (is that a word?). It compresses real nice before its starts to break up. I went with cathode bias and a concertina splitter. I may experiment with a long-tail or paraphase splitter, but "if it ain't broke..." good luck, SteveR
