I need repair info for the Harmon Industries 4200B selective voltmeter to
use as a LF receiver. This is an old instrument, but it is of the vintage
back when I was a technician, so I should be able to fix it - if I can find
where to get a copy of the diagram for less than I gave for the instrument.
Anyone have firsthand knowledge of this thing?
Thanks,
