The real Svetlana tubes are the SED "winged C" ones. They sound fantastic. These are the one's with mojo.
As for 12ax7's...
I have been using the reissue tung-sols and mullards with success. I like them a lot. The mullards seem to be just a little darker to my ears. The Chinese 12ax7c is a nice tube with higher gain than most others being manufactured right now.

Another question....Will the amp have to be re-biased with this tube change or will it be ok where it is?
