Thanks to Tim, I got a scan of the SAMS and was able to make some good progress. I recapped the power supply with 'lytics I had on hand which meant paralleling some caps to get the right values. The new caps are so much smaller that it was no problem finding space.
I powered it up with a metered variac and got a raster right away. Current draw after warmup was about 850 MA from the AC line.
I fed it a signal and made the usual adjustments and got this:
Horizontal and vertical lock are very stable. Obviously it still has some issues, but not bad considering that it's still full of cruddy paper caps! Next, I fed it programming from a cable box. The picture looks pretty good, although the CRT is a bit dim (the brightness is up full). The sound works, but is very buzzy. I'll hold off on making any adjustments until I've finished the recap.
The contrast control is a bit flaky. I cleaned it, but I get the highest contrast in the middle of its range. Again, probably a leaky cap. All in all I'm happy with the first power-up
