Thanks for the comments guys. Last night I got the chassis clamped up on my work cart and started eying the situation over. First impressions are that there's tons of room to work under the chassis, and I like the fact that the electrolytic capacitors are all mounted under chassis, all 12 sections of them.




Unbelievably all 12 cap sections reformed to within spec for leakage current at their rated voltage. Most are below 1ma at 450 volts, not bad for original caps. While I don't condone playing these old sets with original caps, I do find it entertaining to see how they test and hold up under initial use. I'll probably leave these in for initial power up and replace them at a later time. I would never leave a set of this vintage with original caps powered up while unattended.




There's a problem area under the high voltage cage that's going to be a bugger to recap. I think I'm going to end up drilling out the rivets on the horizontal linearity and size control bracket to get at the caps buried down in there. Also discovered the pink 750 ohm sand covered resistor is open, along with the fuse and a previously replaced 10K(green) wire wound resistor. That .02uf cap isn't suppose to be across the linearity coil either. Somebody was obviously having some horizontal issues.
