I would not plug this machine in without finding a manual like this. In addition to setup and normal operating instructions, it has troubleshooting flowcharts, diagrammed mechanical adjustments, and schematics to beat the band. The tech I hand it to would be thrilled to find solder side PCB diagrams with component outlines superimposed, pinouts for every IC chip, and line drawings of transistors, with labeled legs.
As for printing quality, this may be a copy of a copy, but even the finest print when enlarged is very legible. There is a bit of grayed print over a few pages, as if a wet page were placed over it, but the print is still very legible. If you could borrow an original manual and get it printed and bound for 4 to 6 times the cost, you could get better quality. In that case you wouldn't be here. For price, utility, and availability I am rating this manual highly.

I received the Manual in a timely manner and it was exactly what I needed.
This is a perfect copy of the Service Manual, The quality is great. I am very
happy. Thank you
;
exactly as they say. Within 24 hours the link to the pages and offcourse it was the right service manual. Super and thanks

The manual was exact the thing that was promised. My old car stereo is working again thanks to the information supplied.

I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!

� Perform adjustments in the HI-VOLTAGE mode. 1 Adjustment point Semi-fixed resistors VR101, VR201, VR301, VR401, VR501, VR502 of amplifier board 2 Precautions on adjustments 1. Set the RCA input terminal to open. 2. Apply a voltage of 14.4V between the +12V terminal, REMOTE terminal, and GND terminal. 3. Rotate the above semi-fixed resistors completely in the counterclockwise direction while observing the component side. 4. Check that the voltage at the adjustment point becomes 0 mV in step 2. 5. Fine adjustments may be required according to the characteristics of the MOS-FET used. � When adjusting the idling current Rotating the semi-fixed resistor in the clockwise direction: Increases the idling current Rotating the semi-fixed resistor in the counterclockwise direction: Decreases the idling current * Take note that rotating excessively in the clockwise direction will increase the idling current suddenly. 3 Approximate adjustment values Adjust as follows so that the following voltages become 1.2 to 0.3 mV around 0.7 mV . FL channel : Voltage between TP7 and TP6: Use VR101 of the amplifier board FR channel : Voltage between TP7 and TP5: Use VR201 of the amplifier board RL channel : Voltage between TP7 and TP4: Use VR301 of the amplifier board RR channel : Voltage between TP7 and TP3: Use VR401 of the amplifier board SUBWOOFER Channels : First, adjust so that the voltage between TP1 and TP2 becomes 1.2 to 0.3 mV around 0.7 mV using VR501 of the amplifier board. Next, adjust so that the voltage between TP1 and TP2 becomes 2.4 to 0.6 mV around 1.4 mV using VR502 of the amplifier board.� Connection :
