Change CJ Premier 12 to XS ??


Please respond if you have any experience with the CJ amps in tetrode versus triode mode. I am considering having my amps converted to triodes on the basis of articles and reviews, but I have never heard them in triode mode. What I have read says they will be more musical. Any drawbacks other than the loss of power? Thanks.

Thanks Jose... glad to be part of the club. ;> I recently ordered some NOS Sylvania 5751 Gold Brand tubes for these amps... supposed to be the cat's meow as far as 5751s go. (Better be for $62/ea!)... currently have some NOS raytheons 5751s and RCA cleartops for the 6fq7s. (same tubes complement as the 8xs I think... ?) Svets in the El34 positions.

I just boxed these amps up today to send to Bill (ow! my aching back), will be a long 3-4 weeks without them!

It would be nice to be able to switch from ultralinear to triode like some amps can... anyone ever wire up their CJ's like that? (with a swtich).

take care,

Thanks so far for the input. How do I get in touch with this fellow Bill Thalmann you have mentioned? Why would I want to utilize his services over those of CJ?
