Well, good thing is though it's a radio that schematically the same as any AA5, it is a transformer radio and not a hot chassis.
I guess the usual is in order, you know what to do - recap, recarb etc, the only thing I will remind you of - the cap #40 (Mains filter) - make it a Y-cap with the appropriate voltage rating. Don't use regular caps, even if hi-voltage types - only use Y. And do it every time you decouple MAIN to chassis or anything touchable.
