I searched EVERYWHERE looking for the manual/s on this "extinct" amp. Owner-Manuals.com made it available and for nearly nothing. Thanx to them, I can decipher the unknown cables and sort them out. Thanx, Owner-Manuals.com!!

Yes thank you i got the file i was after. There was a slight problem in my communication but it all worked out well.
A job well done.

Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

Very good manual, at a very good price. Received in a timely manner

4-3-4 To Adjust E/F Balance (PLAY mode)
1. 2. 3. Set TIME/DIV of the oscilloscope to 2mS. Set Volt/DIV of the oscilloscope to 0.5V. Ground the scope input and set to DC and then set the DC range. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to center to TP2. Load and play the disc. Turn NVR1704 counterclockwise to the minimum value. Raise NVR1702 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) Adjust NVR1704 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. 2. 3. 4. Set Volt/Div of the oscilloscope to DC 100mV. Ground the scope input and set the waveform to 0V, DC range. Connect the GND terminal of the oscilloscope to Vref, and (+) terminal to center of TP1. Set NVR1701 to 0mV.
