Service Manual that I received was very helpful to me. Thank you.
;
The manual is well organized and is easy to read. The chapters are following normal way to proceed.

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.

REMARKS
67KC Trap (L-6)
Stereo light must be on. This is done by adjusting the "MPX Light Adj." control, R-12.
T-6 top and bottom; L-5
Adjust for maximum voltage
Stereo light must be off.

T-7 bottom core
SAME
Stereo light must be completely on.
T-7 top core
Adjust for stable scope display
1. Turn off 19KC pilot on MPX generator. 2. Adjust upper core of T-7 to obtain a stable and uniform 1 KC signal scope display. This adjustment may be critical, so turn core very slowly. 3. Turn 19KC pilot back on. Modulate left channel and measure right channel output. Adjust L-5 for minimum right channel output (maximum separation). Be sure all test leads are removed from TP#2 for separation tests. Modulate right channel and measure left channel output. Separation in steps 5 and 6 should be at least 30db.
L-5
30db separation or more SAME
This step checks the rejection of 19KC and 38KC frequencies. Residual output should be at least 40db below modulated output. MPX light adjust control R-12 Turn control until light comes on. Then back off just enough to cause the light to go off. Then back off about 1/8 of a turn more. Light should operate ONLY on a MPX signal.
