It's exactly a complete and very useful manual with all details what I needed. Thank you!I will come back whenever I need your manuals or schematics.

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.

7. ADJUSTMENT
ATTENTION
¶ Don� t make speaker terminal short circuit during the power supply injection. ¶ Since the PRIMARY part of the AMP ASSY is not insulated, be careful of electric shock. ¶ Be sure to disconnect the power supply cord before touching the AMP ASSY board. ¶ Discharge the C13, C14 capacitors!
7.1 MEASURING INSTRUMENTS
¶ Provide yourself with the following measuring devices: (1) Digital voltmeter (2) Oscilloscope (3) Attenuator (4) Low-frequency oscillator
7 GAIN Adjustment
(1) Decrease the level of the Adjustment Variable resistors (VR) for the channel to adjusted. (2) Increase LEVEL VOLUME maximum. (3) Adjust GAIN (VR41) volume. ¶ Apply the signal to the Line IN of JA201. ¶ As the gain from IN to SPEAKER OUT 53dB(freq. = 50 Hz), input of 10mVrms to Input results in output of 0.72 W (4.5 Vrms/28 W) at SPEAKER OUT. ¶ After power-supply ON, after waiting abut 10 seconds, it adjustment because, wave form rises behind time for slow start operation.
