Quick site processing. A complete and very useful manual with all details. Thank you!
;
Quick service response. A useful and very rare service manual with all details. I recomend this service.

I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.
;
Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
RX Section Adjustment
1. RX Level Adjustment � Perform the adjustment at T1CH (26CH: 43.780 MHz) as a rule. Setting :
FM RF SSG HAND MAIN board TP2 TP3 (RX GND)
3. RSSI (H) Sensitivity Adjustment � Perform the adjustment at T1CH (26CH: 43.780 MHz) as a rule. Setting :
AF ocillator FM RF SSG HAND MAIN board TP2 TP3 (RX GND) output: 20 Hz
Procedure : 1. FM RF SSG condition : Carrier frequency : 43.780 MHz Modulation : 1 kHz Deviation : 3 kHz Output level : 60 dBµV (1 mV) (EMF) 2. Adjust the FL101 for the maximum reading on the level meter. Also check that the output level is within the specified values.
level meter HAND MAIN board + � TP27 (SP) TP26 (SP)
Procedure : 1. FM RF SSG condition : Carrier frequency : 43.780 MHz Modulation frequency : 20 Hz (EXT) Deviation : AM 50% Output level : 2 dBµV (1.259 µV) (EMF) 2. Use the oscilloscope to confirm the FM RF SSG input (AF) signal waveform and RSSI signal, and use the RV101 so that they are synchronized matched (duty is synchronized).

TP5 (RX VT) TP3 (RX GND)
Adjustment Location: HAND MAIN board (See page 17)
Procedure: 1. The digital voltmeter connected TP5 (RX VT) to TP3 (RX GND). 2. Adjust the L102 for 0.8 V ± 0.05 V reading on the digital voltmeter. Adjustment Location: HAND MAIN board (See page 17)
