Is my amp faulty? Any suggestions on how to fix it?

vyle

I've got a Denon amplifier. Recently, the left channel cuts out every now and again -- not for long, but enough to notice. The amp is well ventilated and so overheating shouldn't be a problem.

When the left channel IS working, the speaker sort of...squeaks when playing mid range sounds, especially when people are speaking. You'll get a kind of ringing/squeaking sound after certain words.

I don't want the hassle of taking it back to hughes if i don't have to, as it's heavy, but if anybody knows a quick and easy way to fix the problem without invalidating the warranty, I'd be grateful to know.

D.K.

My personal experience is that when things go wrong there's a 90% chance its due to faulty plugs and connections. Take them all out check and clean.
Don't know if that's any help?

They can send a man to the moon but they can't make a decent plug!

After the connectors, the next most likely cause will be the rotary controls for volume and balance (and sometimes bass and treble, depending on the design).

The tracks on these wear and can become intermittent. If you lose the sound in one channel and moving one of these controls gets it back, that is almost certainly your problem. They can be replaced, but on old amps it is rarely worth the cost.

The above poster i think is talking about Sound Pots. Maplins do replacement sound pots for a few quid.

After posting this, I had a bit of a fiddle, and, silly me, it's not a fault wit either the amp or the speakers. It was the cable that was linking my tv to the amp. the slightest movement caused the sound to go berserk, so I've replaced it with another spare stereo cable I had lying about and everything's fine.

Thanks for your replies
