Section I: Precautionary Measures
In the Mini-Moog , as in any electrical device, shock hazards exist. All lethal voltages are
confined to the area around the power switch and the A.C. fuseholder. Always unplug the
instrument while servicing the electronics. Keyboard cleaning and adjusting may be done with
the unit turned on.
When a fuse blows, replace it only with the proper size as indicated on the label directly below
the fuseholder. If the fuse continues to blow, it is an indication that a definite electrical problem
has developed. Never try a larger fuse; this will only result in further internal damage.
Avoid making adjustments at random. Each adjustment is critical and should be made in
accordance with the procedures outlined herein. If a sub-assembly is found to be defective, we
recommend exchanging it rather than attempting to repair it. Unless a qualified technician is
available, with special test fixtures, more harm than good may result and possibly void any
remaining warranty.
