TYPE 1263-B AMPLITUDE-REGULATING POWER SUPPLY
1. De voltages are measured with a vacuum-tube voltmeter with 100-
M
D
input resistance.
2. Resistance measurements are made with anchor terminals 21 and
23 connected to ground.
3. Except for V4, measurements are made with OUTPUT VOLTAGE
control and R2 set completely counterclockwise and the CW-1 KC
f1J
MOD switch set on CW. Measurements for V4 are made with the CW-1 kc
nJ
MOD switch set on 1 KC
