NOTES:
(1) Measured by DC VTVM, such as @ Model 410B.
(2) Measured by ¢ Model 428A Clip-On Milliammeter at red-green wire loop between
B+ and R9 (beneath RF Oscillator stator turret contacts).
(3) Measured by ¢@ Model 428A Clip-On Milliammeter at red-green wire loop between
B+ and R15 (beneath RF Amplifier stator turret contacts).
(4) Feedback voltage terminal (4) next to diode detector CR2.
(5) Output voltage terminal (5) next to generator terminating resistor, R18.
(6) Leave dial set at 1 MC, rotate range switch only to desired band,
