[time-nuts] OT - DC-10 gyros

Bill Ezell;

Your Gyro may require 3 phase, 400 cps, 28 vac, Sine wave.

A simple "Buffered Phase Shift Oscillator" for 400 cps can create the Sine Wave.

A "3 Phase Generator" can create the 3 phase output.https://www.circuitlab.com/circuit/m4u5nw/3-phase-generator/ Add 3 Amplifiers (one for each phase) to reach voltage/power.
If the Gyro is directional, it will take several hours to stabilize.
