 ;
very helpfull
circuit diagram and sparepart list available
 ;
Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.
;
I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.
;
It was complete service manual with all needed service informations. Thanks.
APPENDIX IC DESCRIPTION

EXT.R IN EXT.G IN EXT.B IN
Input terminals for EXT RGB signals. The signals are clamped by capacitors, therefore the input impedance should be low, 100 ohms or less is recommended. For this input, the brightness and RGB contrast is adjustable, the ABL/ACL limits the output level. This ABL/ACL may be turned On and OFF. OFF : for small area like OSD ON : for large area like TELETEXT (input level 0.7Vp-p/100IRE) The GND terminal for Y/C circuit. Terminals for R/G/B signal output. Connect resistances to GND, for the current source if the slew rate is not enough. Due to the source current limitation, the resistances should be 2.0 or more.
