The Marconi BD272 transmitters at Skelton were supplied with 11kV d.c. via solid-state rectifiers but used to be supplied via AR64 excitron rectifiers. When they were converted to s/s, the cooling fan was left operational and it came in on a contactor. Failure to close would result in a 'non-urgent alarm'.
It got to the point where the contactors used to stick occasionally, and a kick behind the control cabinet would get it going. On Sender 57 someone kicked it with a muddy boot and there was a handy footprint on 'X' for ages!
