[Boatanchors] Manual wanted for ME-398/U Selective Voltmeter

[Andree Knott]

Dear List Members,

recently I bought an ME-398/U selective voltmeter on a swap sale. When I received this cute meter I found it was defective.

Now I am looking for a manual or at least for a circuit diagram which may help a bit during my attemps to repair this test equipment.

Are you able to supply such a manual, a copy, a scan or maybe a source where I could ask for it?
I would appreciate any help and I will pay for any reasonable expenses of course.

P.S.: It is my intention to use this selective voltmeter as a VLF receiver. I already have a large ring of flexible plastic tube in my garden and a matching run of shielded multicore cable which has some 70 insulated litz wires, from which I will switch some in series and some in parallel, depending on the frequency range. This will make a nice loop antenna...
