Repair or mod CJ PV-12?



The transformer on my Conrad Johnson PV-12 bit the dust. I'm debating whether or not to send it to CJ for repair, or off to get mods and a new transformer. If the mods included a transformer upgrade, that would be a fantastic choice.

Some people here have had good luck with mods, could they provide who did them; from what I've heard they got fantastic results.

Any help you can provide will be greatly appreciated.

Detredwings, all the people who can not hold a soldering iron or read a schematic think everyone else is so afflicted, consequently we have to overlook and at the same time understand the basis for their inability to comprehend what we have presented.

big fan of CJ gear here, keep us posted about your decision on this piece. I will be interested if you allow CJ to do the repair or send it to Bill Thallman or another modder.

Happy Listening!
What is you lived in Alaska or Hawaii and we were talking about a 75 lb amp? It's out of warranty. Any repair station should be able to call and buy a part. Most parts can simply be bought from part suppliers. Transformers usually not. So because that part failed now you get screwed?

That my friend is what is wrong in high end audio. There is not ONE valid reason they can give for their behavior.

The ONLY person to contact is Bill Thalmann at Music Technology in Virginia. He was the chief engineer at conrad-johnson for years and is the foremost authority on repair and mods of their gear. Best of luck!!
Hi Orpheus

Don't know the current status of your transformer dilemma and your decision on what to do. To followup I recently received my upgraded PV9 from Bill Thalmann. No fears with having him do the work and that I can say without reservation. The things I like about the PV9 are retained with just more of everything that I was hoping to achieve, clarity, detail but most notably improved natural and true timbre of instruments and voice all the while retaining that magical CJ warmth and "just sounds right" quality. The improvement at the frequency extremes, particularly the upper frequency extension and air is beyond what I expected and a huge improvement and really comes through on soprano and choral without the edginess I often hear or on the other hand a roll-off that can detract from the performance. I am most pleased with Bill's work and craftsmanship.
