When connections are made to amplifiers, be certain to connect GROUND SIDE of the tuner " output " to ground side of the amplifier unit.
If the tube to line transformer is used, it should be placed a short distance away from the receiver and the proper method of orientation be employed to insure the minimum hum pickup between any power transformers either in the receiver or the amplifier. If it becomes necessary to readjust the setting of the tuning condenser compensators; follow this procedure:
(1) Place receiver in operating condition.
(2) Connect local oscillator to antenna and ground terminals.
(3) Set tuning dial on receiver to 18 " on the dial.
(4) Set oscillator to 1500 K.C.
(5) Adjust all four trimmers for maximum reading on output meter.
(6) Keep power from oscillator at a very low level to assure accurate tuning,
(7) Check at lower frequencies if desired but as the receiver has been designed and the coils and condensers are matched so that "8" on the dial is 1500 K.C., these adjustments should be sufficient for all channels unless the receiver has been damaged.
