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.

CUE/REV Check Play back the tracking alignment tape (XH 2-1) (Ref. No. J-5). Establish the CUE mode. Confirm that the pitches between the peaks of the RF waveform are equally spaced. Also confirm that the RF waveform amplitude at entrance side (B) and exit side (C) is 50% or more respectively, when taking the amplitude (A) in the CUE or REV mode as 100%. Establish the REV mode. Confirm that the pitches between the peaks of the RF waveform are equally spaced. Also confirm that the RF waveform amplitude at entrance side (B) and exit side (C) is 50% or more respectively.

Rise-up Check Play back the tracking alignment tape (XH 2-1) (Ref. No. J-5). Change the modes from CUE mode to FWD. Confirm that the RF waveform rises up within two seconds when the mode is changed from CUE mode to FWD. Change the modes from REV mode (two seconds or more of REV and to the FWD within five seconds) to FWD. Confirm that the RF waveform rises up within two seconds when the mode is changed from REV mode to FWD. Change the modes from STOP mode to FWD. Confirm that the RF waveform rises up within two seconds when the mode is changed from STOP mode to FWD.
