Hi Steve, the Set is Murphy Model U472. All valves are the U series, i will post circuit, and indeed there are caps in the heater chain, unless one or more have gone down, the radio was fine, turned it off, then back on later and the UCC85 on the VHF Tuner head also the UABC80 failed to light. I will check circuit and caps now, i did fit a NOS UCH81 to no avail the heater comes off this, to the tuner head, then to the UABC80 then chassis...regards Alan.
