Repair or mod CJ PV-12?

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.

Tubegroover, I'm glad what you like best about your PV-9 was retained; for us that's a just right sound, we don't care about no stinking neutral.

I just got off the phone inquiring about the PV-12, and was told whoever takes care of it is out of town. No big deal, I wrote a letter and my unit is still at home. Although I wish I had the PV-12, I've still got the PV-10 working perfectly; still got that CJ sound we don't like to live without.

I want to install that transformer before I do anything else, maybe Bill Thalmann could get it, I'll call him

When your audiophile world is right, it seems everything else works out better; my advice to you is, ENJOY, ENJOY, ENJOY.

Ahhhh, neutral, whatever it means as if to say that it is somehow right. The best audio is not "neutral" it is what serves the music in a manner that engages the listener in the performance. If that doesn't happen then neutrality or, another nebulous term, accuracy may appeal to the brain of some that somehow think it "right" but not necessarily to the purpose of music and the end goal. I've given up on trying to reconcile the two, there is none. The only thing that matters is engagement which is less a function of brain but of emotional involvement. While the vintage CJ sound always had an innate "musicality" that is to say engagement factor, improved passive parts can exponentially improve performance and attain greater enjoyment without paying a premium to realize it. The same could be said of many "classic" designs.

I picked up this unit for a really good price and thought it had enough potential to improve on the things I REALLY liked without having to spend a premium for something new. It was a no brainer gamble that worked out quite nicely for me, especially when you are communicating with someone that understands the goals and brings them to your realization. Enjoy the music!
