Manual acquired with good resolution, complete in all its pages, very good policy of the folder where are saved all products purchased.
 ;
Service manual very complete and clear. It was very helpfull for my work.
;
This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!
;
Good price for the manual and easy to locate on the site and download. Plus, just like the original. Thanks a lot.
SERVICE INFORMATION
TOOLS AND MEASURING INSTRUMENTS
NECESSARY TOOLS
Tools normally used for TV servicing are sufficient. Standard tools are listed below. � Diagonal pliers � Long nose pliers � Phillips screwdriver � Flat blade screwdriver � Wrench (size 5mm) � Nutdriver (size 5mm) � Adjustable wrench � Soldering iron � Solder � Vinyl insulation tape � Polishing cloth
NECESSARY MEASURING INSTRUMENTS
� TESTER(VOLTS-DC, AC., Ohmmeter) � Microwave survey meter - Holaday HI-1500 HI-1501 - Narda 8100 8200 � Inch scale � 600 cc non conductive material beaker (glass or plastic), inside diameter: approx. 8.5 cm(31/2 in.) � Cylindrical and made of borosilicate glass vessel. max. thickness: 3 mm outside diameter: approx. 190mm height: approx. 90mm � Glass thermometer: 100°C or 212°F (1 deg scale)
MICROWAVE LEAKAGE TEST
CAUTIONS
� Be sure to check microwave leakage prior to servicing the oven if the oven is operative prior to servicing. � The service personnel should inform the manufacture importer, or assembler of any certified oven unit found to have a microwave emission level in excess of 5 mW/cm2 and should repair any unit found to have excessive emission levels at no cost to the owner and should ascertain the cause of the excessive leakage. The service personnel should instruct the owner not to use the unit until the oven has been brought into compliance. � If the oven operates with the door open, the service personnel should: - Tell the user not to operate the oven. - Contact the manufacturer. � The service personnel should check all surface and vent openings for microwave leakage. � Check for microwave leakage after every servicing. The power density of the microwave radiation leakage emitted by the microwave oven should not exceed 4 mW/cm2. Always start measuring of an unknown field to assure safety for operating personnel from radiation leakage.
MEASURING MICROWAVE ENERGY LEAKAGE
� Pour 275±15cc of 20±5°C(68±9°F) water in a beaker which is graduated to 600 cc, and place the beaker on the center of the turntable. � Set the energy leakage monitor to 2,450 MHz and use it following the manufacturer's recommended test procedure to assure correct result. � When measuring the leakage, always use the 2inch (5cm) spacer supplied with the probe. � Operate the oven at its maximum output. � Measure the microwave radiation using and electromagnetic radiation monitor by holding the probe perpendicular to the surface being measured Move probe along shaded area Probe scanning speed Less than 2.5 cm/sec ( 1in/sec)
