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.

COMPLETE ADJUSTMENT PROCEDURE
usuially a particular oscilloscope will not need
coniplete testing and calibration. Only one or two test:s will be needed and they can be done without conipleting the entire test procedure. following procedures are listed in a recomThe! a merided sequence for complete test and calibraoperation. In general, tubes are the main tionI se of trouble and new ones should be tried cau, befcire making adjustments or component replacemerits. See paragraph 4-4. SPE3CIFICATIONS FOR THE @ MODEL 122A OSCIL,LOSCOPE ARE GIVEN IN THE FRONT OF THIS MA: NUAL. THE FOLLOWING TEST PROCEDURE COTgTAINS EXTRA CHECKS TO HELP YOU ANAL' f Z E A PARTICULAR INSTRUMENT. THESE EX' TRA CHECKS AND THE DATA THEY CONTAIN CAIVNOT BE CONSIDERED AS SPECIFICATIONS.
3) Turn instrument on and measure the output voltage of the internal power supplies (see paragraph 4-9 POWER SUPPLIES). When turning the oscilloscope on for the first time after repair in any power supply circuit, turn the INTENSITY control fully counterclockwise before applying power. Failu r e to follow this precaution may cause permanent cathode-ray tube damage. If you are able to get a small, round, and sharply focused spot with good brilliance by adjusting the controls, the high voltage power supply can be assumed to be operating properly.
4) If necessary, the high voltage can be measured and adjusted as in paragraph 4-8. If R308, High Voltage Adjustment, is changed, adjust FOCUS and Astigmatism (R316) controls at low intensity toobtain a small, round, and sharply focused spot. If the high voltage is changed, recalibrate the Vertical and Horizontal Amplifier Gain.
For' location of the controls mentioned in the follow:ing procedure, see Figures 4-1, 4-2 and the VOlltage and Resistance Diagram at the end of this secition. A fifteen minute warm-up and power SUP1 ply output voltage measurements are always recc2mmended before making any other test or adjListment
.
5) If the cathode-ray tube physical position has been changed, check trace alignment with bezel. Turn TRIGGER LEVEL control fully counterclockwise to AUTO. Set SWEEP TIME switch to 50 MICROSECONDS/CM. The CRT trace should be parallel with the graticule lines. The CRT face should be placed just behind the filter in the bezel. If CRT face and filter touch, a visible interference pattern will result.

T U R N ON PROCEDURE
Perform this procedure only after repair work has been done on the instrument. The purpose of tllis procedure is to check that none of the power SUP1Jlies have been shorted and to s e r v e as a partial rhpi -..-:k upon the correctness of the repairs that have been made.
1) Measure resistances from the power supplies to ground. When measured with an @Model 410B Voltmeter, they should be within 50%of the following:
+ 380 volt supply + 100
4-9
P O W E R SUPPLIES
The power supplies in the oscilloscope are extremely stable and will require infrequent adjustment. The output voltages should be measured with a recently calibrated 1%voltmeter, such as an @Model 405A or 412A, a t regular intervals but unnecessary adjustments should be avoided. CAUTION When first turning the oscilloscope on turn the INTENSITY control fully counterclockwise before applying power. Failure to follow this precaution can cause permanent cathode-ray tube damage.
-150 + 24
50K ohms 50K 12K 5.5K (Remove V1, 2, 4, and 5 to check)
2) Measure resistances to ground into the vertical and horizontal input terminals for all dc switch positions. As measured with an @Model 410B Voltmeter these resistances should read: VERT SENSITIVITY = 1 Megohm OFF = a CAL =a, HORIZ SENSITIVITY I1 Megohm
------------
1) Turn instrument on and allow at'least 15 minutes for warm-up. 2) Turn the sweep generator off by turning the SWEEP TIME HORIZ SENS switch to 10 VOLTS/ CM.
