OK, I am hoping I've worked this out OK, but I've had a double check of the schematic on the trade sheet and the original 16uF smoothing cap positive appears to be the red terminal on the bottom of the can, the 32uF reservoir positive is the other terminal with three yellow and red striped wires, and the black terminal goes to the chassis. So, I am assuming my first tentative test should be to tag the positive from one of the new 33uF 450V electrolytic caps onto the top of the red terminal, and negative to the black, and see how the radio likes that, via the lamp limiter?
