– BACK LIGHT FOR SP2 –

1-2. SCHEMATIC DIAGRAM

Note on Schematic Diagram:
• All capacitors are in 

µ

F unless otherwise noted.  p: pF.

50 WV or less are not indicated except for electrolytics
and tantalums.

• All resistors are in 

 and 

1

/

4

 

W or less unless otherwise

specified.

2

: nonflammable resistor.

C

: panel designation.

Note: The components identified by mark 

0

 or dotted line

with mark 

0

 are critical for safety.

Replace only with part number specified.

A

: B+ Line.

B

: B– Line.

• Voltages and dc with respect to ground under no-signal

conditions.
no mark : AUDIO

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

).

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