Probably it never existed a 1081 official service manual from Commodore, it's look more like a NAPCEC service manual & diagrams compilation of the 1084 series and his variants, like the nap6523, 8cm505, 1084S, 1084P and obviously the 1081. It's more complete than other scans and the quality of the scans also are far superior. It has two circuit diagrams variants of the 1081, mono and stereo versions. It doesn't include a diagram for the Philips CM8500 or CM8501, they look like the 1081 but they are slightly different.

Rapid, clear well done as all the scheme I downloaded from this site. Great job very functional and very useful
;
Great copy of the manual, has all information required for servicing,

I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

really a very good manual even sometimes the quality is no so good as before still very readible and very very useful!
5-8 Output Power of Magnetron
CAUTION MICROWAVE RADIATION
PERSONNEL SHOULD NOT ALLOW EXPOSURE TO MICROWAVE RADIATION FROM MICROWAVE GENERATOR OR OTHER PARTS CONDUCTING MICROWAVE ENERGY. The output power of the magnetron can be measured by performing a water temperature rise test. Equipment needed : * Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm) * One glass thermometer with mercury column NOTE: Check line voltage under load. Low voltage will lower the magnetron output. Make all temperature and time tests with accurate equipment. 1. Fill the one liter glass vessel with water. 2. Stir water in glass vessel with thermometer, and record glass vessel�s temperature ("T1", 10±1° C). 3. After moving the water into another glass vessel, place it in the center of the cooking tray. Set the oven to high power and operate for 55seconds exactly. (3 seconds included as a holding time of magnetron oscillation:) 4. When heating is finished, stir the water again with the thermometer and measure the temperature ("T2"). 5. Subtract T1 from T2. This will give you the water temperature rise. ( T) 6. The output power is obtained by the following formula; Output Power = 4.187 x 1000 x 52 T+0.55xMcx(T2 -T0) 55 : Heating Time (sec) 4.187 : Coefficient for Water 1000 : Water (cc) T : Temperature Rise (T1-T2) To : Room Temperature Mc : Cylindrical borosilicate glass weight
7. Normal temperature rise for this model is 9.3° C to 10.5°C at 'HIGH'. NOTE 1: Variations or errors in the test procedure will cause a variance in the temperature rise. Additional power test should be made if temperature rise is marginal.
