Yes I agree about the ripple current Robin. I used a 16UF 500V 'surge proof' [well that's what it said on the can] for the reservoir. I do stretch a point here but with modern capacitors of good repute, they seem to hold up very well. These 47uf 450V were removed from an almost new switch mode power supply that has yielded eight so far!

These are all normal age related/storage faults and quite straightforward. It's more a case of working out exactly what is going on due to faults in every section of the receiver but I think I may have the better of it now.
The little Vidor certainly appears to have given very good service to it's owners back in 1948. I wonder how many crowded into the living room back then to watch the Coronation on it's tiny screen?
I'm busy over the weekend so it will have to wait for a while. Cheers, John.
