Upgrades for older Conrad Johnson?

Another possibility is to send it to Bill Thalmann at Music Technology.

Bill worked at CJ for a very long time and just might know more about that amp than the current CJ staff (other than Bill Conrad and Lew Johnson of course). I think he was technical director at CJ or something like that.

His website is at the link below. His website even mentions CJ repairs and upgrades. He is the guy on the right of the two pictures. Great guy to deal with. Knows his stuff. Drop him an email or call.

It's been a while. I would have them install edison price music posts for speaker output. tiffany rca jacks. the power switch could be replaced.

A reliable power switch would be nice. Good luck, Dave

Sending it to C-J will get it repaired. Depending on how much more you may want to spend I would recommend that the power supply caps be replaced and purchase the best output tubes you can find. The '75 is heavily biased into class "A" which is hard on output tubes. The Svetlana 6550 tube (the "flying C" logo) is the best bet of the new offerings. The poster above mentioned Bill Thalman. He is an excellent source for upgrades and repairs. He offers an upgrade package for that amp. I have had both my amps upgraded by him and recommend his work.
