This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.

This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.

Well-scanned, complete manual. Contains the information needed for repair and maintenance.
HCD-DX50/RG80
Note : Clear RF signal waveform means that the shape � � � can be clearly distinguished at the center of the waveform.
Adjustment Location: [BD BOARD] (Conductor Side)
RF signal waveform VOLT/DIV : 200mV TIME/DIV : 500ns
level : 0.65 ±0.15Vp-p (RFDC) 1.1 ±0.4Vp-p (RFAC)
E-F Balance (1 Track jump) Check

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

RV101
6. Adjust RV101 on the BD board so that the center of waveform becomes the same voltage of DVC. (i.e. A=0V)
