No clue what year it is, I didn't find any markings. Would the chassis number help? If you can tell me where on the chassis to look, I'll find it. There are lots of numbers there, I just don't know which one is which. I'll look for bad solder joints too. I don't know what it is they used back then (100% lead?), but it sucks. Takes at least a 40 watt iron to melt the stuff, but even then much of it flakes off. Can't imagine it conducts very well at all.
I rebuilt everything in the high voltage cage as well, including replacing all HT wiring, cleaning, recapping, ect. When I first fired it up afterwards, one of the 5U4's red plated and melted. I had mistakenly connected a 'lytic and a mylar in parallel with each other on a B+ line , so..... hope the schematic shows HV in detail, but since it shows a strong raster I'll assume things in there are OK for the moment.
