Thanks so much for the Owner's manual for my Sony PS - FL1. I had purchased the turntable off of eBay. It came in and looked great. Packed well and appeared to be great. I balanced and aligned the tone are and hooked it up. When trying to play a record the tone are would move to the right place and just before it would drop to play it moved back off the edge of the record before touching down. I searched the net for an answer to this issue. No luck. Then I purchased the owners manual and sure enough there was a place to adjust where the stylus touched down. That adjustment solved the problem and saved me a $35 feet to have the player checked out. The manual is well written and easy to understand. It is a must have for anyone with this front loading Sony turntable.
Some years back I pruchased a Sansui G-9000. I had it cleaned up and a problem with the left channel repaired. When I got it back I hooked it up to my tape decks, turn tables, TV and it played great. The only thing I was not really satisfied with was the performance of my Graphic Equalizer. I purchased this owner's manual had poured myself a cup of coffee. The manual is well organized and written in plain language. It also contained the solution to my dissatisfaction. By using the preamp connections coupled I was able to run everything through my graphic equalizer and now enjoy the full potential of my complete system.
An excellent service for the price, however, it would also have been handy if the troubleshooter pages were included. The manual is only sent in the language of your country, thus it looks as though there are some pages missing. Otherwise highly recommended.
I am happy to get a rare TECHNICS SH-9090 Owner's Manual by PDF in clear copy.

Cycle Troubleshooting Guide
Trouble analysis
1. Check temperature difference between intake and discharge air and operating current. Temp. difference : approx. 0°C Current : less than 80% of rated current Temp. Difference Temp. difference : approx. 8°C Current : less than 80% of rated current � All amount of refrigerant leaked out. Check refrigeration cycle.
� Refrigerant leakege Clog of refrigeration cycle Defective compressor
Operating Current
Temp. difference : less than 8°C Current : over the reated current
� Excessive amount of refrigerant
Temp. difference : over 8°C
� Normal
Notice : Temperature difference between intake and discharge air depends on room air humidity. When the room air humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower temperature difference is larger. 2. Check temperature and pressure of refrigeration cycle. Suction pressure (Compared with the normal value) Temperature (Compared with the normal valve) High Higher Normal
Cause of Trouble Defective compressor Defective 4-way reverse valve Excessive amount of refrigerant Insufficient amount of refrigerant (Leakage) Clogging
Description Current is low. High pressure does not quickly rise at the beginning of operation. Current is low. Current is low.
Lower
Higher
Notice : 1. The suction pressure is usually 4.5~6.0 kg/cm2G(Cooling) at normal condition. 2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with putty.
