I would suggest you ship these to Krell, even if you are not warm to the idea. They will replace your caps with most recent version available, check everything up and adjust power supply bias. A local tech can certainly replace the caps, not too sure if he would know how to adjust the PS bias which is important to keep everything running smooth. There could be some proprietary components to be replaced and would think that a local repair shop could not do much for you in this situation.
I have sent my FPB-350MCX monoblocks for recap to Krell and they replaced all caps and amp cover screws. The unit is now running much cooler than previously. You will have to wait 100-200 hrs before the caps are fully broken up and get the tremendous bass back from your Krell, once the job is completed.
