Hi,
It is possible that the main smoothing cap may need changing, but first you might need to find why you are not getting any direct signal through.
If you were able to check the dc voltage at the anodes of the first valve then this would help indicate where the fault might be. I wonder if you have checked the jack sockets as I seem to remember that corrosion on them can cause problems with intermittant signals. if you are not used to high voltages, do please be careful when taking measurements.
