Thank you all for the great info.
I couldn't bear the though of this set ending up in the trash either. Glad to have it...just gotta figure out where to put it.
It was my feeling as well that the power supply had new(er) caps in it. There is absolutely no hum in the audio and those definitely do not appear to be factory caps. I also noted that the wiring harnesses were not in their factor clips, a further clue that the supply had been serviced. That being said, it doesn't appear that the set has had much if any other servicing. All the factory clips seem to be in tact. Pretty amazing really.
