VINTAGE HUNTS CAPACITOR AND RESISTANCE ANALYSER CB3

[djrm]

Likely the caps in the Hunts are better than the ones they sold radio manufacturers.

That was my point, Mike. Rather expensive but looks handy. I have some old diy books showing how to make this kind of bridge though never built one myself. I do have an old GPO line testing bridge used to determine cable fault distances. This was before the ones with a CRT became popular. 

It's a good idea to make a leakage tester though. I have some suitable supplies including an old flash gun. My old russian multimeter needed an external high voltage supply for its high ohms range. I still have that actually it is a small toroidal transformer with some transistors driving it.
