You might want to call Cary to see if you can use the Sylvania 8417 tube. I had an Audio Electronic Supply (built by Cary) AE-25 Superamp and tried dozens of different tubes in the 6550/KT88, EL34/KT77, and 6L6/EL37 families, both new production and NOS. However, it was the Sylvania 8417 tube that blew me away with its transparency, bass depth and control, and midrange magic. No wonder Quicksilver used this late-developing tube in the 8417 monos. As good as the Tung-Sol 6550, Amperex EL34, and Western Electric 350B is, the 8417 was, at least in my amp, in another league entirely. I would imagine the V12 to be able to use this tube and IMO worth a call to Cary.
Alternate Power Tubes for a Cary V12R
Howdy - I've got a Cary V12R that takes dozen EL34 tubes. The tubes are getting a little tired and I'm thinking about replacing them. I like the way the amp sounds, but I'm always looking for a little extra - a bit more extension in the treble and tighter bass. the Cary manual states that the amp can run on 6L6, 6V6, KT-66, KT-88, KT-90, KT-99, 6550C, and of course EL34. I'd like to retain some of the EL34 mids if possible. I'm trying to keep it to a dull roar, maybe $50-$60 per pair. Does anyone have any experience rolling tubes in this amp, what are you using, and what do you recommend? Thanks!
