Took me this long since last post to finish the recapping, this is a tough one for sure. I took my time, and was careful not to break any of the original phenolic can cap thingies. Only thing that remains is gluing the cardboard covers back over them.

On first powerup the voltages were strange, negative voltages all over the place. Ended up being the 9k-ohm section of R154 (a) was open, so I replaced the bad section with a 10k/10-watt sand resistor. Close enough to work. Few more badly out of tolerance or just plain open resistors had to be replaced and I have a picture on the screen, but it's all kinds of out of adjustment. The pots all have tin whiskers in them, so now I descend into the 7th level of hell- rebuilding every pot on this thing, hoping I don't destroy one of them.
