Note on Schematic Diagram:
• All capacito~s are in µF unless otherwise noted. pF: µµF
50WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in U and
1
/4 W or less unless otherwise
specified.
• L : internal component.
• ~: nonflammable resistor.
• [=:J: adjustment for repair.
• Power voltage is supply from TA-H500
• Voltage are de with respect to ground under
no-signal (detuned) conditions.
no mark: FM
( ): MW
< >: LW
• Voltages are taken with a VOM {Input lmpedance 1 0M Q }.
Voltage variations may be noted due to normal produc-
t_ion tolerances.

Note: The component~ identified by mark Lt or dotted
line with mark Lß are critical for safety.
Replace only with part number specified.
