It's great to be able to obtain a precious technical information for a real old equipment. The one I got helps me a lot in the area of wiring diagram to repair my antique. PDF gave me clear enough information to find out thr details. Thanks for giving me the oppotunity to be able to access to almost vanished informations.
Procedure : 1. Connect an oscilloscope to TP (TEO) and TP (DVC). 2. Turn Power switch on. 3. Load a disc (LUV-P01) and playback the number nine track. 4. Press the gG button. (Becomes the 1 track jump mode.) 5. Confirm that the level B and A (DC voltage) on the oscilloscope waveform.
1 track jump waveform center of waveform B A (DC voltage) DVC level=1.0 ±0.5Vp-p symmetry
TP (RFDC)
60 61
RV101
6. Adjust RV101 on the BD board so that the center of waveform becomes the same voltage of DVC. (i.e. A=0V)
