Krell KSA 250 amps

I have 2 Krell KSA 250 amps that were recently bench tested that had been in storage for 10+ years. Each amp had a cap overheat and in the identical place on the input circuit boards. I am trying to sell these amps and realize I have to drop my price or get them repaired. Does anyone have info on what to ask for 2 non functioning amps. I have had an offer so low I can't accept it. Any help or info appreciated. Estimate from Krell is between 600-800/amp. Question is fix or part it out.
