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.

CD ADJUSTMENT
1) Precautions � This unit uses a single power supply (+5V) for the regulator. The signal reference potential, therefore, is connected to VREF(approx. 2.1V) instead of GND. If VREF and GND are connected to each other by mistake during adjustments, not only will it be impossible to measure the potential correctly, but the servo will malfunction and a severe shock will be applied to the pick-up. To avoid this, take special note of the following. Do not connect the negative probe of the measuring equipment to VREF and GND together. It is especially important not to connect the channel 1 negative probe of the oscilloscope to VREF with the channel 2 negative probe connected to GND. Since the frame of the measuring instrument is usually at the same potential as the negative probe, change the frame of the measuring instrument to floating status. If by accident VREF comes in contact with GND, immediately switch the regulator or power OFF. � Always make sure the regulator is OFF when connecting and disconnecting the various filters and wiring required for measurements. � Before proceeding to further adjustments and measurements after switching regulator ON, let the player run for about one minute to allow the circuits to stabilize. � Since the protective systems in the unit's software are rendered inoperative in test mode, be very careful to avoid mechanical and /or electrical shocks to the system when making adjustment. � The RFI and RFO signals are easy to oscillate because of a wide band. When observing them, insert a resistor of about 1 k� to the series. � This equipment will not guarantee the load ejection operation when the mechanical unit is turned upside down. In particular, if the ejection operation is incorrectly performed and recovery is disabled, the recovery is enabled by resetting a product or turning ACC off to on. 2) Test Mode This mode is used for adjusting the CD mechanism module of the device. � Test mode starting procedure Reset while pressing the 4 and 6 keys together. � Test mode cancellation Switch ACC, back-up OFF. � After pressing the EJECT key, do not press any other key until the disk is completely ejected. � If the ] or [ key is pressed while focus search is in progress, immediately turn the power off (otherwise the actuator may be damaged due to adhesion of the lenses). � Jump operation of TRs other than 100TR continues after releasing the key. CRG move and 100TR jump operations are brought into the �Tracking close� status when the key is released. � Powering Off/On resets the jump mode to �Single TR(91)�, the RF AMP gain setting to 0 dB, and the automatic adjustment value to the initial value.
