Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

Good manual. Even it is an old printed manual, it is well scanned and complete, with all drawings, schematics and parts list. Very good return for the cost.
PS-8 PS-8 Test Set Up and Procedure
SYSTEM AURAL SWEEP TEST Equipment needed: � Function/signal generator/sweep generator � Integrated Amplifier � Multimeter � Speaker cables General Unit Function (UUT = Unit Under Test) Switches/knobs on the amplifier faceplate: Low Pass Frequency Adjust full CW (150Hz) Phase switch � either position 1. From the signal generator, Connect both right and left line level inputs (RCA) � not the LFE jack - to signal generator and UUT. Use Y-cable if necessary from mono source. 2. On the amplifier, turn the LEVEL control full Counterclockwise (Min). 3. Turn on generator, adjust to 75mV, 50 Hz. 4. Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max). 5. LED should now be Green; immediate bass response should be heard and felt from rear port tube opening. 6. Turn off generator, turn LEVEL control fully Counterclockwise (Min), disconnect RCA cable. 7. Connect one pair of speaker cables to one set of High Level input terminals on UUT. Cables should be connected to an integrated amplifier fed by the signal generator. 8. Turn on generator and adjust so that speaker level input at the amplifier is 1.5V, 50 Hz. Turn LEVEL control full Clockwise (Max). 9. Green LED should light; immediate bass response should be heard and felt from the port tube opening. Sweep Function 1. Follow steps 7-10 above, using a sweep generator as a signal source. 2. Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofer and test. Driver Function (Woofer) 1. Remove woofer from cabinet; detach + and - wire clips. 2. Check DC resistance of woofer; it should be 4.5 ohms±10%. 3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V. 4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
