Good,readable manual. I found other manuals that were not readable when it came to part ID, but the one downloaded from owner-manual.com was better than expected. I will do buisness with owner-manual.com again.
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.
Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.
TUNER SECTION [AM] BAND switch : AM
NOTE: The adjustment should be performed setting the area indication to âEurâ. (Refer to âReceiving Stations Outside Your Countryâ on page 3.) After the adjustment, reset the area indication as it was. AM RF SSG Put the lead-wire antenna close to the set. 30% amplitude modulation by 400Hz signal output level : as low as possible AM VT VOLTAGE ADJUSTMENT Adjust for following values on digital voltmeter. Display indication Digital voltmeter reading Adjustment part AM531 kHz 1.5V T1
AM VT VOLTAGE ADJSTMENT BAND switch : AM digital
voltmeter TP22 (VT)
[FM] BAND switch : FM
FM RF SSG 0.01ÂµF 22.5kHz frequency deviation by 400Hz signal. output level : as low as possible
[FM VCO Adjustment] Procedure :
FM RF SSG 0.01ÂµF Carrier frequency : 98MHz Modulation : no modulation to ANT (TP1) VTVM 32 output level : 0.1V (100dB) to ANT (TP1)
1. Connect frequency counter to the positions shown below. 2. Tune the to 98 MHz. 3. Adjust RV1 for 19 kHz Â± 100Hz reading on the frequency counter.
frequency counter TP23 (IC2 Pin !â¢) 1ÂµF 100k (IC2 Pin 9)
â¢ Repeat the procedures in each adjustment several times, and the frequency coverage and tracking adjustments should be finally done by the trimmer capacitors.
