Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

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.
HTP-940 ADJUSTMENT PROCEDURE
SKW-940 : POWERED SUBWOOFER / ADJUSTMENT OF IDLING CURRENT
[When] 1. Exchange transistors (Q505 - Q519). 2. Exchange MAIN PC board ass'y (NAAF-8829). [Procedure] <Note> No speaker load and No input signal. 1. Short test point P631 for amplifier is under active mode. 2. Adjust the trimming resistor R544 so that the reading of multimeter becomes 52 ohm to 53 ohm. 3. Connect the DC voltmeter to test point P531. <Fig-1> 4. Connect the AC power cord into a wall outlet. 5. Press POWER button to turn on the unit. (MPP type only) 6. Confirm the voltage of above point after 6 minutes to 8 minutes. (Heat running) 7. When less than 3.20 mV : Readjust the trimming resistor above so that the voltage becomes 4.5 mV to 5.0 mV. When 3.30 mV to 5.20 mV : Not necessary to adjust. When 5.21 mV to 10.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.0 mV to 5.5 mV. When 10.1 mV to 20.0 mV : Readjust the trimming resistor above so that the voltage becomes 5.6 mV to 6.0 mV. 8. Press POWER button to turn off the unit. (MPP type only) 9. Disconnect the DC voltmeter. 10. Disconnect the AC power cord from a wall outlet.
