Re: Marconiphone VRC74DA
I acquired my VRC74 in the late eighties. It had well and truly been butchered.
A rheostat device was fitted on the cabinet side and this was connected up to the heater chain, presumably it was adjusted to compensate for variations in the mains voltage. There was also some pretty adventurous wiring to the radio receiver which in this set is a completely separate unit. The radio chassis is actually made by Plessey.
After all the circuits had been tidied up the set does work surprisingly well. Very bright CRT.
