NOTE: All DC voltages measured with a 1000 ohm-per-volt meter from ON-OFF
switch (-B) to socket contact indicated. All AC voltages are measured
from ON-OFF switch (-B) to socket contact indicated.

All voltages are positive DC unless otherwise marked.
Volume Control full on. No signal.

The following equipment is necessary to properly align this chassis:

A signal generator which will provide an accua

rater calibrated signal at the frequencies listed.N0TE;

An output meter.
Dummy antenna: _ .1 mfd. -.RMA loop.

may

Intermediate Frequency and Oscillator adjustments
be made with the loop disconnected provided a`
resistor of 10,000 to 50,000 ohms is substituted to
close the 123A'7GT grid circuit. The loop alignment
must be done with the loop and chassis mounted in
operating position in the cabinet, A single turn loosely
coupled to loop may be substituted for RMA loop.
