RE: Modified Futterman OTL amplifier

Posted by Lew on June 2, 2008 at 07:12:47:
I don't know how I might have helped, but it sure looks cool. One reason it may sound better than some other Futterman designs is simply due to the use of the 6SN7, presumably at the input. I tend to think the 6SN7 outshines most 9-pin miniature dual triodes or the pentodes that are used in the classic Futterman circuit.
