Sounds like the main smoother is O/C and the strange sound is probably the line timebase trying to work with loads of ripple on it. You say you have some radio values.
Even these clipped across should considerably improve the hum situation and get it going to some extent. Maybe 32uf or something similar. Make up some croc clips and just clip a couple across the old smoothing block. See what effects it has, failing that I can probably find you a large NOS telly multi block that you can experiment with. PM if you would like it. Regards, John.
