Excellent manual, detailed, very useful! Exactly what I needed, I'd recommend it to all who need it. Although images are scanned easily readable and explicit. A valuable tool product at a price more than modest, take it with confidence and you will not regret it!

Clear and complete service manual. Easy now to restore my old Kenwood KD-1500.
Thanks a lot.

Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !
 ;
Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.

This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.
HANDSET SECTION
Note: � Apply 3.6 V dc from regurated DC power supply. � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. � Set to handset manual test mode. (Refer to page 9) TX SECTION ADJUSTMENT TX VT Adjustment Setting :
digital voltmeter
RX SECTION ADJUSTMENT RX LEVEL Adjustment Note: � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. Setting : VOL switch : M
FM RF signal generator
+ �
TP6 (TX VT) TP30 (TX GND)
TP2 TP3 (RX GND) Carrier frequency : 43.780 MHz Modulation : 1 kHz Deviation : FM 3 kHz Output level : 60 dBµV (1 mV) (EMF)
level meter
+ �
Procedure : 1. The digital voltmeter connected TP6 (TX VT) to TP30 (TX GND). 2. Adjust the L52 for 0.9 ± 0.05 V reading on the digital voltmeter. RX VT Adjustment Setting :
digital voltmeter
TP26 (SP) TP27 (SP)
Procedure : 1. Adjust the FL101 for the maximam reading on the level meter. Also check that the output level is the specified values. Specified Value : �9.5 to �15.5 dBV
+ �
TP5 (RX VT) TP3 (RX GND)
RSSI Hi Adjustment Note: � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. Setting :
AF oscillator FM RF signal generator
Procedure : 1. The digital voltmeter connected TP5 (RX VT) to TP3 (RX GND). 2. Adjust the L102 for 3.0 ± 0.05 V reading on the digital voltmeter.
Output: 20 Hz
TP2 TP3 (RX GND) Carrier frequency : 43.780 MHz Modulation : 20 Hz (EXT) Deviation : AM 50% Output level : 5.5 dBµV (1.88 µV) (EMF)
