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

I've read somewhere CJ doesn't really like to do recaps on old gear so looking for some guidance.  Costs?

I vaguely remember hearing this as well. I own/owned the MF-2300A and PV-14LSII. What I can say is that I’ve contacted cj multiple times through email and they’ve always been transparent and responsive with their repair estimates. If I was in your position, I’d try sending them an email. Side note of interestingness: I’ve been told that cj doesn’t like to share their schematics - unsure if this unique or common?

If we're talking PS caps, which really should be done every 25-30 years with modern caps, you don't need a schematic.  The caps will be labelled in big bold numbers. Any tech can do them.

I'd leave the signal caps alone.  At the point where you start chaning those you'll just want a new piece of gear. :)

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!
