"Broker"
Getting started on restoring my pile of CR-1020 receivers... somehow I ended up with 5 of them. 3 were working, 2 not... This is one of the non-working ones (far right above - the other two are on the shelf, still in their case) - I figured I'd start with the one in the worst shape. I didn't even try turning it on... just dug right in. This one is tentatively sold to a local guy who will be using it in his warehouse, so his primary concern is power, and a good tuner. So I will not be touching the tone amp or phono amp sections.
It was quite dirty - a lot of nicotine staining inside, so I took the front frame right off and opened it up. ("Smokey one" refers to the smoke staining... not necessarily that it had actually "smoked," but who knows - it may well have at some point)
The silver areas are clean from where parts were bolted to them... I went through a few paper towels soaked in alcohol - cleaned up quite nicely. (for some reason I didn't take any "after cleaning" pictures)
The bottom of the power & protection board:
All cleaned up, there is a lot of damage here - not sure why.
I discovered the following work has been done here already - 4 resistors changed on the cap board (the 10 & 22 ohm replaced with 3w), outputs replaced on one side of the amp, the wiring for the 234 transistors... I checked the resistors and found them in good order, outputs are good... so I set about re-capping and re-building.
