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!!
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

Tracking Balance Measurement 1) 2) 3) Connect the oscilloscope to test points TP-TE and TP-VC. Playback the second track of TCD-782 and press the PAUSE button. Check that the traverse waveforms of the oscilloscope are up and down symmetrically.

Laser Current Check * Perform this check only when the laser is faulty. 1) Connect a digital multimeter across the resistor R541 (10 ohms). 2) Playback TCD-782 and check the DC voltage value of the 3) 4) digital multimeter. Check the SPEC VALUE specified on the label of pickup. Calculate the laser current (Iop) by diving the DC voltage value across R541 by the resistor value (R541 = 10 ohms). Check that the laser current (Iop) is SPEC VALUE ± 10 %.
