Downloaded the manual, reasonably straightforward, pretty much exactly as advertised.
 ;
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.

TROUBLE SHOOTING TABLE (Continued)
Checking the output PWB unit
Are there signal inputs at No SC1404, SC1405, SC1501 and SC1502? Are voltages applied to EA connectors and SC5502? If there is no signal at EA connector or SC5502, go to Yes Checking the power unitblock.
No
If there is no signal at SC1501 and SC1502, go to the video system block.
If there is no signal at SC1404 and SC1405, go to "Trouble shooting table for PC I/F unit".
Are there signal outputs at pins (14) ,(16) and (18) of IC1401 ?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal inputs at pin (47) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal outputs at pins (17), (19), (21), (27), (29) and (31) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1101,IC1201,IC1301 and their peripheral circuits.
No
If there is no signal input at pins (1) and (24) of SC1101, SC1102 and SC1103, check the switching circuit and amplifier circuit of IC1101, IC1201, and IC1301, and their peripheral circuits.
Are there signal inputs at SC1101, SC1201 and SC1301? Yes Yes
No
Check the R, G and B panels.
If there is no signal input at pins (8) and (23) of SC1101, SC1102 and SC1103, check IC1409 and their peripheral circuits.
Check IC1406, IC1407, IC1408 and their peripheral circuits.
