What tubes are you using;CJ Prem.5

i'am using the svetlanas,my CJ PREM5's are in triode mode,i had my amps modified by bill thallsman,BILL retired from CJ
last year,he held the position of technical director and designed most of their tube gear up to 1999.bill also changed the pwr cord and hardwired them with tiffany tpc50,
the speaker terminal strips were removed and replaced with cardas 5 way binding post + the input rca's were also replaced with cardas rca's,the major changes were performed inside,internal critical wiring was replaced and some other
technical changes were done.the amp's sound incredible.

Fonsy,How much $$, how much turnaround time?? I figure 400 in shipping each way,from CA.,so I may have someone local do the IEC thing, for starters.Most important; what brand of tubes? Do you agree with my assesment on the tubes I have? Thanks for taking the time to respond.

Let's start with the tubes.when i first purchased my 5's,I used tesla el34's did not care for them,bass was muddy and the tubes are very unreliable,called conrad johnson and they put me in touch with BILL THALEMAN,the electrical designer of these amp's,after the modification's bill recommended the svetlanas el34's,the mids are very warm,the treble to die for extremly liquid and absent of any grain,the bass is very musical a great improvement over the tesla's.cost of mod's will run about $500 a pair,i supplied the pwr cords.
turnaround time can run 3 to 4 week's.my amp's were in a a/b comparisons with the CJ8a's which retail for over $15000
tha 8a's were a little better in the bass department that's about it.

avguygeorge,here's bill thaleman tel.# 703-764-7005,he's shop is located in springfield Viginia.i should mention that before purchasing my CJ5's i own audio research vt200,sonic frontier power 3's,CJ 12's and 11a.all the above are fine amp's,but the 5's are magical in triode mode.if your pair is in excellent to mint condition i would serioulsy consider the mod's.any question's give bill a call,he's a true music lover and a gentleman to talk to. good luck.let me known what you decide to do.

Thanks indeed Fonsy. Mine must be in great shape. I can't believe how it walks over my newly re tubed Def.7 Mid to top end just as you describe. Sure sounds like the 500 mod is money well spent.We also agree on the sound of these two tubes. In the unmodified state the Siemens more of the top end /female vocal /piano/magic.Thanks again.
