Excellant!!! Very quick and easy....Best $4.99 I have spent in a very long time..
I highly recommend this.

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.

Certification
Eligible to bear CE marking. Conforms to European EMC Directive 89/336/EEC. Meets applicable tests and performance criteria in European EMC Standard EN 55103 (1996) parts 1 and 2 for residential (E1) and light industrial (E2) environments.
Signal-to-Noise Ratio
78 dB (IEC 651)* at 94 dB SPL
*S/N ratio is difference between microphone output at 94 dB SPL and microphone self-noise A-weighted.
OPERATION
Power
The SM81 requires phantom power. This may be supplied to the microphone by a mixer, preamplifier or console with builtin phantom power or from an external power supply (such as the Shure model PS1A). Phantom power sources providing between 11 and 52 Vdc are suitable. Use only high-quality cables because intermittent shorts between broken shield wires and balanced conductors will cause extremely large noise transients in the system. Avoid ground loops due to grounded connector shells or the microphone case touching other grounded metal objects. Follow generally accepted audio grounding practices.

Polarity
Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3
Cartridge Capacitance
54 pF
Impedance
A minimum load impedance of 800 � or greater should be used for maximum signal handling and minimum distortion. The load may be as low as 150 �, but a reduction in output clipping level will result. It should be noted that the power supply itself may add loading (3300 � in the Shure PS1A power supply) to the microphones.

PS1A Power Supply
When using the Shure PS1A to phantom power the SM81, connect the microphone cable to the SM81 and to the MICROPHONE connector of the power supply. The power supply uses the balanced audio cable pair to carry the supply current to the microphone and the cable shield as a ground return. Connect the OUTPUT connector of the power supply to a low-impedance microphone input of a mixer, audio console or tape recorder. A second SM81 may be connected to the remaining power supply channel in a similar manner.
