INSTRUCTIONS FOR REPLACING THE POWER SUPPLY DIODE PACK  IN MICRO 75A

Stand the unit up (carrying position) and locate the chrome handle cover. Slide a screwdriver under one end of the handle cover and it will pop off. Remove the two bolts holding the handle in place. Lay the unit down (normal playing position) and take off the lid. On the opposite side from the handle are two rubber feet. Take the bolt out of each of the rubber feet. The whole unit will slide out of the case and there is easy access to all parts.

The diode pack is a plug in type of circuit board -- no soldering required. Locate the one in your set, unplug it and plug in the new one.
