 DP-86DA MITSUBISHI Service Manual by Sam Kapasi;
This manual is for the usa model only. But it is clear , accurate and comprehensive, including board layouts and schematics. I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

 A-103 TEAC Service Manual by Mike Dunn;
For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers). Yes, there are free manual sites out there, but if they don't have what you want, you have to pay. And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures. My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse. Schematics and text are clear. I'll be happy to purchase from here again. Mike mikeinthemountains@gmail.com

NOTE: To prevent the tape from damage, turn the guide rollers slowly. (7) By operating the tracking button (both in + and - directions) in the manual tracking mode, vary the output level of the FM waveform from maximum to minimum and vice versa to confirm that the waveform varies nearly in a flat shape. (8) When the FM waveform breaks in the level varying process, subtly adjust the height of guide rollers at every breaking point so that the waveform varies as flat as possible. Repeat the above steps 6. and 7. several times to confirm that the waveform is flat as a whole. (9) Playback the SP stairstep signal of alighment tape and adjust the tracking control to maximize the FM waveform, confirm that FM waveform variation is always flat. (10) Record the signal and play it back in both of the SP and EP modes, and confirm that the FM waveform is flat in both modes. NOTE: Among the above-mentioned adjustment steps, the items of No.9 and No.10 are needed for the EP model only.

Fig.3-3-6 (11) Through the above steps, confirm that there occur no wrinkling and damage in the tape around the PINCH ROLLER and TU GUIDE POLE whenever the deck is in operation of Loading/Unloading, Search Rewind and at mode change from Search Rewind to play mode. If wrinkling or damage in the tape occurs around the TU GUIDE POLE, adjust the angle (slant) of the A/C HEAD to the tape. So that the tape normally runs along the lower flange of the GUIDE POLE.

Fig.3-3-4 Remove the Cover (JIG) shown on Fig.3-4-1. Connect the JIG CONNECTOR CABLE to CN25 on the MAIN BOARD ASSEMBLY as shown on Fig. 3-2-2. Observe signal at V_TP_FM with external trigger from V_FF on the JIG CONNECTOR CABLE. Playback the SP stairstep signal of the alignment tape and maximize the FM waveform by the tracking button. Set the tracking control to the center position by simultaneously pressing the tracking (-) and (+) buttons and maximize the FM waveform by the tracking button. If the observed FM waveform is not flat, adjust the height of the SUPPLY of TAKE-UP GUIDE ROLLER with the roller driver.
