Conrad Johnson Mf-2500a amp and PF-1 Preamp Recap?

CJ gear is top tier equipment and well worth fixing if you are going to keep it. The 2500a gets lots of love from its owners. I recapped my CJ PFR preamp and it was well worth the $$$ spent.

PS - In the case of large PS film caps, those will probably outlast all of us.  CJ does use a mix in their preamps. Just replace the electrolytics.

As a longtime CJ owner, I would ask this question on the CJ owners group site. There are a number of individuals with a great deal of institutional knowledge you may find extremely helpful. CJ also has information posted on their website regarding which vintage items they will upgrade. You could also pick up the phone and call CJ regarding your equipment. The owner, Jeff, frequently answers the phone. The best time to call is between 9:30 - 11:30 am EST. If you don’t live near CJ’s shop in Virginia, the cost of shipping a heavy amp etc. is expensive. Someone on the owners group may know a technician they know and trust near you.
 

As previously mentioned, If you don’t plan on keeping the equipment, it’s probably not worth the cost of servicing the equipment, especially if it is functioning flawlessly. Sell or trade up if you have the $$$$. Best of luck!

@rubicon15 I cannot figure out how to find or get to the cj group you mentioned. I live in Tampa Fl so you are correct… super expensive to ship 2 ways. Only tech I’m aware of in our area is called Proaudio and I do believe they do good work. I will likely approach them but wanted to be able to give them direction (based off of advice here) on what to quote on.

Here is the link. Big Dog RJ is very knowledgeable. However, he lives in Australia. He may be able to point you in the right direction or share a few contacts stateside. Just join the group and post your questions. https://www.conradjohnsonowners.com/
