This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

But documentation was useful.

Adjustment Preparations Adjustment Procedures (1) Turn on the set and perform (1) Turn Vs ADJ to adjust Vs voltage pre-heat run more than 1 to be within ±0.1V of the value min with burn-in screen. specified in the label on the panel.
Remarks Permissive level of voltage in sufficient time of heat-run performed is: Vs: within±0.45V Va: within±0.55V
(2) Receive full back pattern signal (or Video silence signal; it will be automatically turned off after a few seconds by power save function.)
(2) Turn Va ADJ to adjust Va voltage to be within ±0.2V of the value specified in the label on the panel.
(3) Connect voltmeter leads (3) Reconfirm that Vs voltage remains to Vs (or Va) and GND within ±0.1V of the specified value. test points of the power unit. Readjust if it� s outside of the margin.
