Howdy people, I'm a newby here but I've been a fan for awhile of the SX Pioneer silver face receivers. I have been picking them up here and there for a few years but it seems as if each one has it's own peculair problem (not holding FM stations, AM sections etc.) . Anyway, my real question is this; I have a very nice SX-880 right now in my garage that I just switched out an ailing SX-780 for. The 880 sounds great, all tuner sections work well, the problem is that it shuts off when turned up near or over the 8 to 9 o'clock position. It will come back on with an audible (from the receiver, not through the speakers) click when I turn the volume back down. I really don't want to take it in for work and I have done some simple repairs on these type of things in the past, any help would be appreciated, thanks.....Mark.
