Hi. I have a Rotel RA-935BX amp. while adjusting the Bias I accidentally slipped with the probe and shorted out pin tp2 to j36 what looks like a bridging wire, resulting in a blown fuses f901 and f902 [all positions are taken from pcb markings]. When I replace the fuses and power ON the amp the ON led flashes for a second and same fuses blow again and all goes dead. I think I have probably blown a 2SB817E transistor. But I would like to ask if there is anything I can check to see what I have damaged and how to check it. I have wiring manual but being a newbie I don't know where to start checking. I do own Fluke 112 rms multi meter and I'm not too bad with soldering iron but that is where it ends. Thanks in advance for all your help. Greg
