;
Very good quality download here. Great hard to find manuals at a reasonable price.
 ;
I had a problem with the mains transformer, I did not know the voltages on the secondary, this manual helped me to solve this problem, thanks for the 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.
