I inherited a North Atlantic 214C phase-angle voltmeter -I thought how cool, much easier than using a scope...
nope, it's the 400 Hz only version
(fixed filter module). I may run out of 400 Hz measurements in my lifetime.
So, if I could find a schematic or hear from someone who has already invented this wheel, changing the filter to a variable one seems like a good idea.
Any thoughts? (Like use the case, cannibalize the rest?)

Take it to a small avionics workshop and see if they want to swap it for some nice teflon insulated cable.
Haha, that's where it came from...they didn't want it anymore
I've got my third differential voltmeter that doesn't work..how cool to have mechanical readout to a microvolt! But I guess it would have to be working & compared to a real reference.
Thanks, though.

Hi Murray,
That unit could be worth a few bucks if it's in good working order.

Once upon a time I was a tech in a Precision Calibration Lab (PMEL) and worked on those units. Brings back some memories!!
