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.

It is OK, this manual help me to repair my dynacord

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.

I'm very satisfied with my purchase. It resolved my problem. Owner-manuals.com is a very very good place.
Thank you!

1) If sensitivity of frequency counter is too low adjust to max. channel separation
2) RC network serves for damping the IF-filter while adjusting the other one.
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
