Run capacitor replacement

[Reece]

An across-the-line cap ought to be replaced with an X2 safety cap, designed to fail open rather than short. Sal's and Just Radios have them, as well as other sources. X2 for across the line, Y2 for line to ground. There is also a cap rated X2Y2 for either use.

These are AC rated non-polarized oil filled motor run caps. They are used for the resonant circuit of the VRT (voltage regulating power transformer)... Modern VRT isolation transformers spec out the same type of cap as 70's SS consoles like Jon's and Zenith CCII sets do.

Nah, this is another cap, under the chassis:
