Here's that same ARVIN 444A from the previous picture. Here, the case has been stripped, re-painted and the chassis restored with new caps, replacing any out-of-spec resistors, new polarized line cord and Safety caps. BTW, This radio as wired by ARVIN, had an original unpolarized line cord. One line (either hot or neutral) is wired to the switch then to the B- rail. Hanging on this rail is a 330K and 0.05uf cap in parallel then to the case/chassis. If the cap shorts or leaks, that chassis will be hot depending on which way the plug got plugged into the wall outlet. My restoration re-wired the switch so the hot side is switched and then to the plate and heater string. The neutral is now tied to B- rail. And that 0.5uf cap is now a Safety cap. Plays pretty well for not been re-aligned.
