specified.

•

f

: internal component.

•

: fusible resistor.

•

C

: panel designation.

• X

: parts extracted from the component side.

•

: Pattern from the side which enables seeing.

• Indication of transistor.

: B+ Line.

•

B

: B– Line.

•

H

: adjustment for repair.

• Voltages and waveforms are dc with respect to ground

under no-signal (detuned) conditions.

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

Voltage variations may be noted due to normal produc-
tion tolerances.
