Hi Graham,

Thanks for the reply, and for the suggestion on how to restuff the cans. I think, if I am not mistaken, that only the top right connector on the 0,1UF section is connected to ground. At least there is continuity between the top right connector and the chassis/ground, and not continuity between any of the other connectors and ground. Could always be a short somewhere perhaps? Electrolytic capacitors of 1500V is not really easy to find, and probably not cheap? My best bet would be to couple four 450V in series and match the capacitance and voltage required for each, right? And as for the the 0,1uF, is that most likely an electrolytic as well? These mystery multi-section cans are only the start of this enigmatic radio. There are six other normal looking capacitors inside, all with capacitance values in CM. I read that 1000cm is approximately the same as 1100pF?

I'll attach a few more pictures. The brown electrolytic 10uF is now changed with a modern one.
