Fuse Replacement, AC Power Cord | Adcom GFA-6006, GFA-6002 instruction

The proper fuse values are:

GFA-6002 for 120 volt operation Fuse Rating: 5 Amp 250 Volt Buss®: AGC-5/250V Littlefuse®:(3AG) 312005/250V

GFA-6002 for 230 volt operation Fuse Rating: 3 Amp 250 Volt Buss®: AGC-3/250V Littlefuse®:(3AG) 312003/250V

GFA-6006 for 120 volt operation Fuse Rating: 12 Amp 250 Volt Buss®: AGC-12/250V Littlefuse®:(3AG) 3120012/250V

GFA-6006 for 230 volt operation Fuse Rating: 6 Amp 250 Volt Buss®: AGC-6/250V Littlefuse®:(3AG) 312006/250V

Before attempting to replace a failed fuse, be certain to unplug the AC Power Cord from the AC wall outlet to prevent possible electrical shock. Replace the AC fuse only with one identical in type and rating as printed on the rear panel.

DO NOT USE ANY SUBSTITUTE FUSES WITH DIFFERENT RATINGS OR VALUES. Failure to observe this precaution may cause serious damage to the amplifier circuits, may create a hazard fire, and may void the warranty.

If the Power LED does not glow, it may be an indication that the AC fuse has blown. If you are using the 12V DC Triggering feature it may be

possible that there is a problem with that connection. To determine if the problem is caused by a malfunction in the 12V DC system, remove the small plug inserted into the I2V DC Triggering jack. Press the front panel power switch to turn off the amp, and immediately re-press the power switch. If the problem is caused by the 12V DC triggering circuit the amp will turn on and the LED will glow. DO NOT attempt repair of the 12V DC system. If you are not sure or the amplifie displays other symptoms, please consult the RESOLVING PROBLEMS section.

Fuse Replacement

Since the fuse has a ceramic body and you cannot visually examine the fuse element, it is suggested that you replace it with an identical substitute or bring the fuse to your ADCOM dealer so they may check its integrity.

[11] AC Power Cord

The AC cord provides power to operate all the GFA-6002/6006’s circuits. Its plug can be connected to a standard wall outlet provided the outlet supplies a voltage compatible with the power requirements printed on the rear panel of the GFA-6002/6006.
