This service manual is a good copy of the original, complete and fully readable. It is really useful to repair my Tv set following its clear instructions.

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.
