•

X

: parts extracted from the component side.

•

p

: parts mounted on the conductor side.

•

¢

: internal component.

•

: Pattern from the side which enables seeing.

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

W or less unless otherwise

specified.

•

C

: panel designation.

•

U

: B+ Line.

•

H

: adjustment for repair.

• Voltage is dc with respect to ground under no-signal

(detuned) condition.
no mark : PB
