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?)

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!!
