What EL34's for MusicMan?

[drewl]

So, what EL34's you guys running in Music man amp that can take the brutal pounding the 700v Plate voltage?
Yeah, I know they run the screens low, just asking opinoins!
Loose/intermittant sockets probably helped kill the JJEL34L's that were in it.

Well ages ago I used some Svetlana's which took it ok but I gather the ones you had in it (JJ EL34L) are probably one of the best.

I'm new hear and own a Music Man 212 HD... I still have the origional Sylvania tubes which are great but I like to run the JJ EL34 or the GT EL34M.

The Sylvania's are 6CA7s and sound way different than the thin bottle EL34.

[khingpynn]

please describe the difference in sound.

The MM amps are thier own animal as far as sound goes. But in a standard output section a'la Marshall the American "fat bottle" 6CA7 is brighter and cleaner...more like a 6L6. The european skinny bottle EL34 is a tad darker with more midrange fur and breaks up earlier. They look nothing alike and really don't have that much in common. The 6ca7 is a beam tetrode, the EL34 is a standard power pentode.

If you've ever played an old Traynor with those 6CA7's you can hear the difference.

6CA7EH's anyone ?
Just wondering if anyone has tried the ElectroHarmonix 6CA7's
They get glowing reports here:-

Not yet, EH gets ripped for stealing classic tube names, but I recently tried their Genelex KT66's and thought they sounded very nice.

I have JJ EL34L's in my Lynch Box... they have 6L6 qualities in the tone... tighter punchier and more focused... still a wash or wall of sound if you will, like a classic EL34 Marshall tone.

I hear you on Music Man amps being a tone all thier own but in truth they are loosly based on Fender ccts from the old days. The idea being the MM are overbuilt and run like a Indie car.
