Yes, I have. I've also screwed with it a little, using inductors to get a cleaner bass response. It is a very powerful circuit topology, and the inverting gain stage can be a single 12ax7 section. It would be a cleaner circuit with even more gain, say with an EF86, but to be honest I LIKE the way it sounds when it's got a stinkin' hot signal cranked into it. I normally shy away from NFB, but in this case it is so localized as to be unobtrusive. Wire it up and try it out, I think you'll be impressed. ~KG~ |
