Recapping Krell FPB-Monoblocks - Need Advice

I have a flawless pair of original Krell FPB-350m’s I purchased from the original owner several years ago local to me. I am kind of on the fence as what to do, They definitely need a recap as one of them is heating up now and shuts off after 25-30 minutes. I’m debating recapping with upgrades or selling them as is and trying out Parasound JC-1’s or a Pass Labs X250.8. If I do recap them is there anyone in the western United States that can work on them? Krell is back east and wants $1300 per amp and I would have to pay shipping across the country. That would cost me around 3k. That seems quite high for a recap. Is there a dramatic difference sound wise when having these old amps rebuilt with modern caps?  If I do sell them as is what could I roughly expect to get out of them. I am clueless As to what they are worth? My system consist of Egglestonworks Andra II speakers and a AYRE K-1XE preamp. Any advice would be appreciated.

total recap is not necessary most of times. you need to go over caps exposed to high temperatures and voltages. measure their parameters before replacement. if parameters are within specified tolerance and no visual damage, leave them back in the circuit.
if your unit still works nice, you don’t have to do that.
Definitely don't go for $1300 per chassis deal. Not needed and not necessary.

where did you get the information that recapping FPB monos is 2 hours per amp?? That's absurd!!! 2 hours is only to break down chassis components before even getting into circuit boards
