Hello Dave,

This set uses the following valves; DK92, DF91, DAF91, DL94 which are all battery types so there should be no visible glow to be seen from their heaters. If there is then switch off immediately! Steve's statement below is spot on;

I have to agree with Andy's assessment regarding the LT supply not reaching one or more of the valves. I've had this problem before in other Vidor sets which use McMurdo socket bases. The forked pin clinchers tend to fracture in the socket and so lose contact with the valve pins.

Regards
