The original specs for KT77 can be found here:
http://www.tubezone.net/pdf/kt77mov.pdfWhile GEC quotes 32W, they don't necessarily *recommend*
that KT77's be used that way. In fact they state the life
of the tube is going to considerably shorter if you operate them
that way.
Basically, a KT77 is a beam tetrode that's interchangeable
with EL34, like the large bulb 6CA7.> Is JJ/Tesla *really* building KT-77 tubes for guitar amps, or are

use in guitar amps (the GE 6550A is one I can think of, the old
Sovtek 12AX7WXT another). Guitar amplifiers are just a variety
of AC audio frequency amplifier, albeit a mobile one, so the tubes
have to handle being bumped around when the amplifier is moved.Different strokes for different folks, some folks are going to like
KT77's for the kind of music they want to play, others aren't.
