Question about Adcom GFA-5002 Amplifier

1 Answer

Adcom GFA-5002 is dead no lights, no anything

I have a adcom GFA-5002 that is hooked up to a hole home audio system. The two zones that it supports are a deck and a great room. THe deck has no sound at all. The great room is only playing one speaker (pair). The wires will tone to all speakers. The amp is completly dead. Will not turn on. Would that be a fuse or a dead amp?

    I will try a fuse. I hooked a toner to the speaker wires and all the speakers toned. So I don't think the speakers are the problem. If the fuse was bad, would that cause the amp to appear "dead"? (no lights, nothing happens when I hit the power switch, and I even unpluged the amp and plugged it back in and nothing happen)

Check the Fuse. Unplug the AC first. If you replace the fuse and it blows again, disconnect all speakers, replace the fuse and turn on. If the fuse does not blow, chances are it is a speaker problem, Adcom builds some very solid product, I would suggest pulling the outdoor speakers and testing them.
Depending on what you are using, some outdoor speakers should never be taken out of the living room. If you still have an issue post a comment and I will help some more.

    Yes, when the fuse is bad, it's just like pulling the AC cord. Chances are good that your speaker wires are ok. Do you know what kind of speakers are on your deck? alot of the older, so called "outdoor" speakers used a foam surround which will disintegrate rather quickly and expose the voice coils to moisture an seize them up, the amplifier see's this as a dead short and will either go into protection or blow the fuse.

I turn on the ADCOM GFA-5802 amplifier... ...The power light comes on, but does not heat up nor output sound


Have it serviced. Do you know what GFA stands for. People at Adcom do have a great sense of humor. Take it only to a high end audio servicer. Contact Adcom. This is good stuff you wouldn't want a hack working on it.

Adcom gfa 555 blows the 10 amp fuse and the 6 amp fuse on the far right


Any fuse blowing is caused by a shorted component in either the power supply section or main audio amp part. Follow the fuse circuit and see where it leads you. Look around for burnt of damaged parts. Suspect anything sitting on a heat sink. The most common culprit is the audio amp main transistors, especially if someone shorted the speaker leads together. In the power part it could be the transformer, the large Electrolytic capacitors, rectifier, or voltage regulator. Some amps use an IC for amplification and this can blow the fuse.

ADCOM GFA 5802 POWER AMP NO SOUND, BUT POWERS UP.


Remove the output transistors and measure each of the sets of 3 pads and report the voltage readings here. I suspect that you have either a blown driver circuit or output transistors. The voltage readings will give me an idea on where to start looking for specifics.

Thanks,
Dan
