Heathkit IB-2 Impedance Bridge - clean *Limited Test /As-Is* Needs Calibration Airguide The stamps are presented onThis is a gorgeous, and very clean Heathkit IB 2 Impedance Bridge, which I bought and assembled in ~1971. The unit is very clean and has just a a few nicks and scratches. I've let go of most on my bench gear, so I can't tell you how well it works today. One thing for sure, it will need recalibration since I haven't used it since the '80s. I'm selling this as is, but all the tubes light up and everything looks functional.
