What tubes are you using;CJ Prem.5


Picked up a pair of these. I got 2 sets of tubes. One set is the Svetlanas. The other is Siemens / both el34 Highs much better w/ Siemins; Svets/better mid to low bass also more dynamic. One tube do both?

Avguygeorge: Your quite welcome, but Fonsy deserves all of the thanks. Wait until you get these things back. Then you will be really thanking him. If love the CJ 5's now, I'm sure your going to be in awe when you hear it with the mods. I don't want to mis lead you. I have not heard Fonsy's amps, but I've known him for a while now & he & I have very simular sonic taste. If he says it's incredible,it is. He tells it like it is. We both feel that just because a component cost a lot, that doesn't nessasarily make it sound great. I can't wait to hear your reaction when you receive these amps back with the mods. Most of all, enjoy....sagger
I also have a set of these (on loan but I may buy them soon if the price works out ok). I retubed them with Svets - good call on those, I think they are the best. also tried some JJ/Tesla E34Ls, which were nice but the Svets were better, smoother. I also did the small signal tubes, those made a nice difference. Went with RCA Clear-top 6FQ7/6cg7s (NOS, 1960s) and for the 5751 used a 1963 NOS Raytheon. Have heard good things about the Sylvania Gold Brand 5751 but those are hard to come by.

I believe Parts Connection(?) also has an upgrade kit for these amps for about $120, (http://www.partsconnection.on.ca/public_html/tpc/pkulist.html) which replaces some components. after reading this stuff I may (if I buy these) end up sending them to Bill T. to have him do the mods mentioned above as well. (sounds like they are worth it). Would be nice to have IEC power cord capability.

thanks and let us know your results.

sorry, that URL above is wrong, they redid their site... (Parts connection). will repost the new URL if I can find it.
Hi there Ed,welcome to the party.Out of curiosity,what amps have you had recently? My take/in stock form/ this is the best mid & treble I have ever owned.( much better than my Jadis7 mk4. however, bass is way better with Jadis)
Thanks! I've had a few. Currently in my 2-channel system I have the CJ Prem. 5's, a 47 Lab gaincard, and a Classe CA-200. Also have HK Citation 24 (SS), Dynaco Stereo 80 (SS), Rotel RMB 985-Mk2 (SS). these are my first venture with tubes in amps. THey are quite liquid and smooth, I can only wonder how much better they can get with some Bill T. mods.. (?). I haven't heard any Jadis however... but that seems to be pretty highly regarded by some.
