The General Radio 1611-B Capacitance Test Bridge} was introduced in Catalog P (1959) and remained available through Catalog S (1965).
The Type 1611-B self contained capacitance bridge operating at 60 Hz. It can be used at 120 Hz with an external oscillator and filter, the Type 1214-D is recommended. Capacitance measurements at 120 cps are used primarily for the measurement of polarized electrolytic capacitors. A 6E5 "Eye" tube is used as the null indicator along with a detector sensitivity control. The bridge is suitable for testing of paper, mica, and electrolytic capacitors with 1% accuracy.
Specifications
