Marconi Valve Voltmeter TF1041C - repair thread
Hello forum,
I've started work on a Marconi TF1041C Valve Voltmeter which I aquired from a fellow member here.
Condition is excellent, internals look like factory.
It hinges open from the front to give good access to the PSU and meter
Probes look intact and in ok condition.
It also has the original round pin 5 amp fuse-less plug which I want to keep, it fits nicely into the top lid (nice one Marconi).
Taking my time with this, dont want to ruin it.
First order of business... the large 25v 3000uF cap is reading virtually open, about 10Mohms resistance (dropping as I measure it) and virtually no capacitance reading.
Any chance this will reform?
And if yes, what current is recommended to start with?
Thanks
Ray
