Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted.  pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in 
Ω
 and 
1

W or less unless otherwise
specified.
•
1
: fusible resistor.
•
C
: panel designation.
Note on Printed Wiring Boards:
• X
: parts extracted from the component side.
• b
: Pattern from the side which enables seeing.
•
U
: B+ Line.
•
H
: adjustment for repair.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.

).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
