I just purchased a Linn AV5103 pre amp and Linn AV 5125 Amp for a grand total of $10. The owner's son, and I quote, "Over-drove it" and damaged "something". I haven't plugged in the unit's to investigate yet. I don't expect the pre-amp is damaged, but perhaps the amplifier is.
Does anyone have any knowledge of what the problem could be, if I can/should repair it myself, or should/could I send it to Linn? I'm not terribly interested in spending a lot of cash on it. But it would be a fun project to repair.
