Vintage Sprague Transfarad Capacitor Analyzer Model TCA-1.

Description

This unit is only partially tested.
Printout of manual is included.
The bridge circuit is working as seen in the pictures, but i cannot figure out how to test the leakage circuit.
This unit is used to test incredibly minute amounts of leakage in capacitors.
It appears to have been modified at some point as noted by the extra switch on the front panel.
The voltage for leakage testing is present at up to 180v.
This unit is very heavy, close to 20lbs.
Feel free to ask questions.
Thank you for your interest.
I have more vintage electronics as well as test equipment in my other listings.
