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.
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.

â¢ â¢ â¢ Check.
Symptoms that indicate need for maintenance â¢ Block-type noise â¢ Head hole clogging â¢ Tape damage
<Rollers> â¢ Replace if there is anything abnormal in the rotation, or if there is run-out (that becomes large). <Other than the above> â¢ Clean the section that contacts the tape (especially the lower drum helical section). Use the specified cleaning liquid.
Replace the drum ass'y if the video head is cleaned but the envelope still does not appear. (When the envelope is normal, refer to "11. USEFUL TIPS".)

(1) When replacing any part, always replace the cut washer that was removed with a new one. (2) This mechanism does not have control adjustment. If the control cannot be set as required, clean and or replace parts. (3) On the oil a) Always use the specified oil. (Using another kind of oil can cause various kinds of trouble.) b) Always use clean oil, without any mixed-in dirt, to lubricate bearings. (Using oil with dirt mixed in can cause the bearings to wear or to stick.) c) One drop of oil is the amount shown in the Fig. 1, on the point of a pin. (4) Perform circuit repair, tape running adjustment, etc. with the cassette controller assembly attached to the mechanism. (5) When operating the mechanism separately, apply voltage to the loading motor. However, the terminal voltage must be DC3V~4V. (When the mechanism is connected to the main PWB, do not apply external voltage to the loading motor. It may cause a trouble.) (Forcing the gears to turn by hand entails danger of breakage.) If the mechanism is separated from the unit, the capstan motor may rub and be damaged if spacing under the mechanism is inadequate. (6) To install the cassette controller, push section A in the Fig. 2. Do not push anything else. (7) Do not deform any of the mechanical parts.
