I BOUGHT A PAIR OF INFINITY VINTAGE SPEAKERS THAT REQUIRED TO BE REPAIRED AND THE ELECTRONIC TECHNICIAN ASKED ME FOR THE SERVICE MANUAL.
I TRIED TO GET IT AT THE MANUFACTURER'S SITE WITH NO SUCCESS, SO I STARTED TO LOOK FOR IT IN THE WEB FOR A LONG TIME, UNTIL I FOUND THE SERVICE MANUAL IN THIS EXCELLENT SITE "OWNER'S MANUAL.COM".
NOW I HAVE MY SPEAKERS WORKING AND ENJOYING THE MUSIC I LIKE.
THANKS TO "OWNER`S MANUAL.COM" I RECOMMEND THIS SITE TO EVERYONE.
;
Very quick response. Very good and accurate print quality of the scanned document.
 ;
The service manual was very usable and clear enough to see the individual values of all of the components (unlike some of the service manuals I have gotten in the past from web sites similar to this one). The price was right and the information was greatly appreciated. It helped me with an otherwise very difficult repair. It was much needed and appreciated. A faster turn around on my order would be nice, but I understand the constraints on your staff's time. Thank you for your service.

Excellent manual. Helped me out with disassembling and troubleshooting my projector.

thanks you are the best.Very good detail, Quick service response. A useful service manual with all details.
PIF ADJUSTMENT
No. Adjusting point 1 Adjusting procedure/conditions Waveform and others Note: For the 50 ohm signal strength gauge, when not using 50/75 impedance adapter, signal strength is 52 ±1 dBµV (50 ohm open), instead of 54 ±1 dBµV (75 ohm open). precaution: The loss of using impedance adapter. No. Adjusting point 1 Purity adjustment RF-AGC 1. Receive �PAL COLOUR BAR� signal. check cut in » Signal Strength: 54 ± 1 dBµV (75 ohm open) adjustment (PRE SETTED) 2. Connect the oscilloscope to TP210 (Tuner�s AGC Terminal) as shown in Fig. 1.
PURITY ADJUSTMENT
Adjusting procedure/conditions 1. Receive the GREEN-ONLY signal. Adjust the contrast control to have a beam current to 700 µA. 2. Degauss the CRT enough with the degausing coil. Note: Follow the Job Instruction Sheet to adjust the magnetic field. Vertical Bv : -0.050 mT (-0.50 gauss) Horizontal Bh: +0.020 mT (0.20 gauss) (See page 12.) 3. Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. 4. Observe the points �a� and �b� as shown in Fig. 2-1 through the microscope. Adjust the landings to �A� rank requirements. 5. Orient the raster rotation to 0 eastward. 6. Tighten up the deflection coil screws. » Tightening torque: 108 ± 20 N (11 ± 2 kgf) 7. Make sure the CRT corners landing meet the �A� rank requirements. If not, stick the magnet sheet to correct it. Note: This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 700 µA. Note: Set the service mode by TP1001 and TP1002 (short) then press factory process R/C RGB key to change to RGB mono colour mode. Waveform and others

3. Drop Input Signal strength to 51 ±1 dBµV (75 ohm open). 4. Under 1. and 3. conditions, the output voltage should be no change or below +0.1 V. In addition, change input signal strength to 57 ±2 dBµV, the output voltage should be no less than -0.1 V. 5. Change the antenna input signal to 63~67 dBµV, and make sure there is no noise. 6. Turn up the input signal to 90~95 dBµV to be sure that there is no cross modulation beat.
