Default Re: Marconi Valve Voltmeter TF1041C - repair thread

Ray, have a look at the attached picture, I extracted this from a '1041B write off. Currently the parallel combination reads 61 ohms and the temperature is currently around 20C so at 156 ohms for the thermistor it would seem to be in working order.

Yours for the cost of postage. I will confirm how much it is tomorrow.
