pulled the chassis, wow, a lot of work been done. there is a can cap that was epoxied to the chassis rather than using the factor mount location, there are a LOT of not early disck caps (dipped looking ceramics) that are soldered on to the resistor leads, maybe some on was trying to decouple RF. There are some nichicons like a .1 250v that has a 78 on it (1978?), just a mixed bag, some metal film resistors, still some wax papers but it looks like most of them have been replaced. Looks like most of the orig electros are still there but for the one that was expoxied in. I calls for a 12KP4 but it has the 12LP4A so I am guessing this set has seen a lot of use, and a lot of service. Most of the cap replacement was done using the lay the wire by the old wire and flow solder. Its done pretty neatly so maybe that was a common practice back in the day (I have seen J hooking used, and I use pig tails when working around delicate parts). I have not seen this practice before. At least there is no electrical tape/wire nuts type repairs. All those disk are odd since I don't see any evidence of an old cap being removed where these disc end up going.
I have a sams for this coming so it should be interesting to see the schematic. I peered in at the fly but did not remove the cage for a close up exam. From what I could see there was no distress. Wish I knew the history as to what side lined it since clearly someone was into gettting it fixed.
