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.
