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!

5. PCB PARTS LIST
NOTES:
� Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. � The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. � When ordering resistors, first convert resistance values into code form as shown in the following examples.
47k � � 47 � 103 � 473 ........................................................ RD1/4PU 4 7 3 J
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 � � 56 � 101 � 561 ........................................................ RD1/4PU 5 6 1 J
0.5 � � R50 ..................................................................................... RN2H R 5 0 K 1� � 1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k � � 562 � 101 � 5621 ......................................................
