Great.
Not encouraging, but based on a lot of experience with fixing SS power amps.
The Marantz output stage is a pretty straight-forward full-complementary
circuit. The protection circuit (H705-H708) looks a little more complex than
most. More hair-trigger than standard, it appears.
I was told on another forum to check the speaker
protection relay so hopefully it's just that.
Dream on.
I dont think I'm that lucky though. Here is a link to the
service manual if anyone wants it.

Thanks for the link. I always wondered what the schematic looked like. This
was a quality piece - little was spared given the technology of the day.
