Re: Svetlana EL34,is it good sh**t ?
JJ EL-84's are currently the best bang for buck, and most EL-84 fans are using them. The real fun should be experimenting with 1st position pre tubes, to see how good you can get the preamp in your AC-30 to sound.
I'd probably go with JJ power tubes, a Tungsol 1st position, and whatever's in it for the rest. Sovtek and JJ make good rectifier tubes.
