Kenwood KR-100

I am surprised that there is no thread on the Kenwood KR-100 receiver here on AK yet? I've seen a number of them around over the years and have one myself that has issues. It has a reputation of unreliability and appears to have a too small heatsink for a 70watt combined output. Does anyone have one and had experience troubleshooting it?

Here is a web photo (not mine):

I own one. I plan to restore it over the winter sometime. It's not working right now. I haven't diagnosed it entirely, but I know that one of the outputs is blown at minimum.
