Was listening to the rig for the first time in months Friday night, when one channel went out. Thought it was speaker at first, but swapped leads, and no....it's the amp. W/ gain turned up high, I can hear a little sound coming through. Think this is a blown fuse? Dunno why, no shorts or transient spikes or the like.

Thanks

Hard to say what it is with any certainty. But fuses are one of the first things you should check. If it is a blown fuse and you replace it and it blows again do not continue to replace the fuse as something else is wrong.

Obviously, Dont have the unit plugged in when your opening it up. Check your connections too before you open it up.

Spare fuse is in the IEC outlet, take some care when opening that piece.

I know it's not the fuse on the mains, as the amp is still powered. Aren't there internal fuses on the outputs?

There were internal fuses on the Adcoms I had years ago, but they only blew if someone turned on the pre-amp (which didn't have soft start) after the amps were powered up.

There are two fuses per channel, they are on the circuit board near the rear. I believe they are 6.3Amp but it's been too long since I've looked at one.

Hi Joseph, nice to read you, yoou say there is a low sound coming out from damaged channel...


I hope you didn't push the amp louder so it didn't got more damaged.

I think it should be a fuse, 6.3V as good MGalusha said.

Whenever a channel sounds lower or like a bad reception radio station thaen there is a big chance it is only a fuse.
