TL;DR: The conductivity bridge derives its bridge source from a self-contained vacuum tube oscillator adjusted to approximately 1,000 cycles as mentioned in this paper, which operates directly from the A.C. power source.
Abstract: The new Conductivity Bridge derives its bridge source. voltage from a self-contained vacuum tube oscilltor adjusted to approximately 1,000 cycles. Voltage for the amplifier and null indicator tubes is provided by a.builtin D.C. power supply which operates directly from the A.C. power source. 9-324 Conductivity Bridge, without Conductivity Cell, for use with 110 volts 5060 cycle A.C. 9-351.Cosi~uCvity Cell, for use with Conductivity Bridge, constant 0.8, $20.00
