Thank you, this is a rare document. Few others have it, but they charge way more for a download.
Great deal (even if you have to wait a few hours to get it).
;
The purchased manual is an high quality scan of the original Philips paper-based Service Manual. I am very satisfied!
 ;
The purchased manual is an scan of the original Panasonic paper-based Service Manual. Unfortunately the contrast is not perfect, but I am satisfied anyway!
;
The purchased manual is an high-quality scan of the original JVC paper-based Service Manual. The Service Manual includes the Owner´s Manual, so you do not have to buy both of them.
;
It paid to find this Service Manual, couldn't find it anywhere else. Exactly what I wanted. Received within 24 hours.

1) If sensitivity of frequency counter is too low adjust to max. channel separation
2) RC network serves for damping the IF-filter while adjusting the other one.
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
