It's been quite a struggle to find accurate service info. I thought I got lucky when I found original Sylvania service info in Riders vol 24, but it's incomplete.
Nothing seems to quite match exactly but I think I finally have a plan of attack.
The schematic from Riders is easy to read and matches, while the photos from Sams 472-1 match my component layout.
The cap mounted on the top of the chassis in particular
With this knowledge in hand, I'll undo some of the modifications and clean it up.
There are a few oddball valued and high voltage caps I had to order.
0.0056uF @ 1,600 volts for example. They'll be here in a few days.
Meanwhile, I took out the upper chassis. Quite easy to do.
* Pull the knobs
* Disconnect the speakers
* Remove 3 screws
* Carefully slide it out
The PCB is in great shape with no lifted traces. I'll try my Hakko desoldering on it.
