5-15. SCHEMATIC DIAGRAM – WOOFER AMP SECTION – (DR70L ONLY)
Note:
• 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
1
/ W or less unless otherwise
4
specified.
• U : B+ Line.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : FM
