Huge thanks again Fredrik, that is what I was thinking of but was afraid to connect my meter to it
So, another question arose while sourcing some components and hoping other can benefit:
The replacement for that (single) large capacitor in power supply - you picked
much larger capacity but same voltage, which is exactly opposite as other caps (capacity count and voltage can be highrer), right? If yes, why?
I am now seriously chasing one 800 or 1500

Ah, I just got one super-rare receiver on my desk, mint and already recapped -
Pioneer IN All-Wave Stereo Receiver KX-550, a black-face Pioneer from 1970.
So rare that there's near-to-zero information to be found on the web - but tracking SW 3-18Mhz (three scales) tells that it was for some unusual radio listening (GIs abroad?).
