AP3000 AND AP3400 SERVICE
Quick Fix for M1002 and M1002A
To speed up the servicing of the AP3000 or AP3400 on your bench, Yorkville Sound’s service department has developed a method to replace the components most likely to fail when a M1002/A amplifier board requires service.
This Quick Fix kit contains the procedure, assembly drawings, and components to perform the Quick Fix to a M1002 or M1002A board.
It should be understood that the person using this procedure knows how to test resistors, diodes, and transistors to determine if they are defective. This procedure is not intended to be a substitute for one’s lack of electronic capability.
Before starting, look at the board for repair and locate the version number. It is very important that you follow the procedure for the appropriate circuit board version number.
A complimentary service manual for the AP3000 power amplifier is supplied with this M1002KIT.
