brensabre79 Posted June 6, 2011 Share Posted June 6, 2011 I recently bought a Hartke A100 Kickback for practicing. Got it home, practiced for an hour, all fine. Then it started making a squeaking noise - a bit like a signal generator, continuous but falling in pitch very slowly (like a badly tuned radio). When the limiter kicks in the noise stops temporarily but as soon as the light goes off it squeaks again. The first time I turned it off, waited for the thud, and on again all fine. 5 minutes later the squeak is back. Not sure if its temperature related because now i've left it a while the squeak has gone again. Any ideas? Cheers B Quote Link to comment Share on other sites More sharing options...
icastle Posted June 7, 2011 Share Posted June 7, 2011 It sounds like a defective capacitor. If you've only just bought it then take it back. Quote Link to comment Share on other sites More sharing options...

It was a good price even for just the speaker so might just take it to be fixed. Anyone know a good amp tech near Brighton? Quote Link to comment Share on other sites More sharing options...
