Conrad Johnson PV10A Mods/upgrades


Hey everyone..

I'm looking to get both my CJ PV10a preamp and MF200 solid state amp refurbished and upgraded. I've read several recommendations for Bill Thalmann and Bob Backert... who both seem to do excellent work! I was hoping to reach out to you all and see if anyone could chime in and help me decide who to go with? I'm leaning towards Bill Thalmann as he was technical director for 25 years at Conrad Johnson.. Any advice would be greatly appreciated! Thanks!

Lloydelee21,
I would hope that at $20k, there isn't anything that could or should be done to the GAT. :)

Joethekid72,
Years ago I had Bill Thalmann convert my PV-10AL to a 10A by adding the phonostage to the unit. He also upgraded the capacitors and RCA connections and it sounded much better at the frequency extremes and had better clarity as a result.

In communicating with Bill at the time, he said that he knew just where c-j had compromised the design in order to come in at its price point and therefore, where the most cost effective modifications should be made.
