The service manual was a copy of the original from Wirlpool. The quality was good, all neccecary information was available including the service-codenumbers, so I could order the right part to be replaced for repair.
Downloding was no probem after the payment.
Thanks for the service!

Good,readable manual. I found other manuals that were not readable when it came to part ID, but the one downloaded from owner-manual.com was better than expected. I will do buisness with owner-manual.com again.

Service Manual that I received was very helpful to me. Thank you.

The manual is well organized and is easy to read. The chapters are following normal way to proceed.

This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only.
SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE
When servicing the high voltage system, remove static charge from it by connecting a 10K ohm resistor in series with an insulated wire (such as test probe) between picture tube ground tag and high voltage lead. (AC line cord should be disconnected from AC outlet). 1. The Picture tube in this receiver employs Integral Implosion protection. 2. Replace with tube of the same type number for continued safety. 3. Do not lift picture tube by the neck. 4. Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions and servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed: 1. When repairing the circuit, be sure not to increase the high voltage to more than 25.5 KV, (at beam 1000µ�) for the set. 2. To keep the set in a normal operation, be sure to make it function on 22.4KV±1.5KV (at beam 800µ�) in the case of the set. The set has been factory - adjusted to the above mentioned high voltage. Always check the high voltage if there is any possibility that it might have changed as a result of the repair. 3. Do not substitute a picture tube with unauthorized types and/or brands which may cause excess X-Ray radiation.
BEFORE RETURNING THE RECEIVER
In addition to the above checks, the following safety checks should also be carried out before returning the unit to the user. 1. Inspect all leads and dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts. 2. Inspect all protective devices such as non-metallic control knobs, insulating fish papers, cabinet backs, adjustment and compartment covers or shields, insolation resistor-capacity networks, mechanical insulators etc.
