[R-390] Capacitor tester...

[Barry]

While there are lots of choices, one of the nicer things about the Tel-Ohmike and other testers like it is the ability to put a bias on the device under test (DUT) and measure leakage.  I have a General Radio 1617B that will do that.  I just bought a Marconi TF-1313 that's supposed to be a 1/4% bridge but doesn't have quite the voltage bias capacity of the Sprague or the GR.

I've wanted to get a nice, accurate digital cap meter for a long time but just haven't wanted to put down that much money for one yet.  I don't really need that kind of accuracy for boatanchor work.
