Hi There. My cousin entrusted me with repairing/modyfying his amp to a usable state. He has the Line6 Spider Valve 112 and was told by other technicians that the DSP chip need replacement but wouldn't want to take the risk themselves since they are scared that the heat used in removing the chip will damage the components near it. I have not powered up the amp yet since I don't have a guitar to test it with and I'm not sure what can be used as a valid test signal. The DSP board has the same text written underneath the ribon cable connector ( A15: SV MAIN #35-00-0250 REV A 8June2007) I'm still waiting for my cousin to get back to me as to what he experienced was wrong with it. I also noticed that the two resistors R58 and R59 looks 'burnt' they are covered under glue but there is yellowish marks and the value markings of the resistors aren't that readable anymore Is there maybe an indepth manual to the electronics? (long shot, I admit) Any Hints? The heatsink mod seems very good. well done :) Thanks
