Schematics and service manual for Krell FB250M

Can someone send me a copy of the schematics service manual, one amp gets very hot and shuts itself down, led goes out at power up another issue. my tech needs the schematic to bias the faulty amp. I and tech hunted for this info but couldn't find anything at all, like bias voltage and offset voltage.....etc. another tech(but he's away for holiday, tired/ overworked) also said amps looks pristine and caps are healthy, was thinking of recapping too, is doing so good?
