W or less unless otherwise specified.
• f : internal component.
• 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.
• H : adjustment for repair.
• Power voltage is dc 6V and fed with regulated dc power supply
from external power voltage jack.
• Voltages are dc with respect to ground under no-signal (detuned)
conditions.
