I have EL34's in my '73 PTP Super Lead. What could I expect to change if I put in KT66's? Thanks
Were those NOS KT88s? What brand?Not quite the same, but I just swapped out KT88's for the EL34's in my XTC and the difference is phenomenal!
If you like beautiful chime try some big bottle Sylvania's,bestsounding EL-34's i've tried.What about other alternate tubes for EL34s?
If your talking about Sylvania "Fatboys" they are not EL34s, but rather 6CA7s. They are a direct replacement for EL 34s but have a different internal structure. They are what EVH used on his early records apparently. And they are indeed great sounding tubes. I prefer them over EL34s, as well as 6550s-KT88s which I like better than EL34s but not as much as Fatboys.If you like beautiful chime try some big bottle Sylvania's,bestsounding EL-34's i've tried.

The Fatboys are Sylvanias, though they are often branded RCA, Phillips, GE, etc., and have been out of production since the 80s. EH makes modern reissues but they don't sound the same. They're not cheap but they are supposed to be the most rugged and long lasting so if you like the sound they're worth the money. They are a direct replacement for EL34s, so they can be put in any EL34 amp with just a bias adjust. Not so with KT88s or 6550s. I have no experience with KT66/77s but I'm guessing that they are like the KT88s.To install the Svetlana Fatboys or KT66/77/88's in a Marshall, do I have to do anything different internally or can I just plug them in and bias them and then go to town?
