This piece is one of several I picked up at an estate sale in June. It’s late 60’s / early 70’s vintage, making it one of the newer pieces in my collection (and by far the newest thing I’d picked up that day).
This killed two birds with one stone: I’ve wanted an Impedance Bridge for quite a while, and oddly enough, I didn’t own any General Radio gear until now.
This is actually an after picture
Wrapped carefully in extra-wide gaffers tape for structural integrity. Because gaff.
I tested a cap or two as well which seemed to work and indicate that the internal oscillator is functioning. It’s an interesting, if not somewhat fickle instrument. The sensitivity control is overly sensitive, which I suppose bears some investigation. It’s not nearly as foolproof as a modern LCR meter, you need to have some idea of the value you’re expecting, or it’s possible to get a false reading.
