* All capacitors are in uF unless otherwise noted. pF:yF
50WV or less are not indicated except for electrolytics and
tantalums.
¢ All resistors are in Q and 1/4W or less unless otherwise
specified.
. % : indicates tolerance.
. A: internal component.
* [~~]: panel designation.
- ([EEESE: B+ Line
+ (RES: B-Line
¢ [_]: adjustment for repair.
* Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PLAY
( ) : REC
* : can not be measured.
¢ Voltages are taken with a VOM (Input impedance 10MQ).
Voltage variations may be noted due to normal production
tolerances.
* Signal path.
