After checking resistors and transformers, I usually start by replacing the filter caps and on this set its a multisection capacitor can, C13, with 54/40/10 uF using twist tabs to lock the can into the mounting. In some sets I've cut the can off while it is still attached to the chassis thus eliminating resoldering at least some of the connections on the underside. Unfortunately I did not see an easy way to cut the can off; it was tucked in between the 1st IF, the tuning cap and the speaker. I suppose I could have taken the speaker off and in the end that might have been the better way to go but I decided to dismount the can after disconnecting everything that was attached to it. Unfortunately access to the underside C13 was difficult owing to multiple paper caps and resistors in the way. There were something like 10 or 11 wires, caps and resistors connected to the can leads and/or twist tabs. I took notes and they all match the schematic so I should be OK for reassembly. I attempted to simply untwist the tabs for the can removal but two of them had enough solder still on them that it was proving hard to slide the tabs out of the mounting wafer. After numerous attemps to desolder, ultimately I drilled out the rivets on the mount. The cardboard came off easily with a little heat (there was just a bit of tar at the top of the can holding it on.) I doubt I can get a rivit gun back in there for reattachment so a couple of machine screws and nuts will have to suffice.
