I was having a hard time finding the problem with this Mackie 1604 unit. I didn't have a schematic. Went looking on the web and found your site and the price was more then reasonable. Ordered it and within the hour had the manual and within 15 minutes had the unit fixed. Best $4.99 I ever spent. Thank you.

This is a service manual in every sense of the word ( French and German versions of the text are included, as well as English..)
There are explanations of the mechanical and electrical functions, plenty of mechanical drawings, and the needed schematics. The quality of the scanning is excellent - all the component values are clearly legible - and very usefully there are pcb component layouts, so you can find a component on the schematic, and then very quicky pinpoint its physical location on the relevant pcb.
I cannot see how I can give this manual any less than the maximum 5 stars! Great value for money, which will pay for itself immediately. Excellent all round!

hat alles sehr gut geklappt. Das Servicemaual ist gut zu verwenden. Die Pläne und Schrift
ist klar und leserlich. Außerdem preiswert. Grüße an alle Hifi-Bastler
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.
