Hi, im just registered but have gawked at a lot of TB posts, it's a great forum. I have a big problem with an SWR redhead that was given to me. It's a wonderful little amp, but there's an intermittent popping and crackling, kind of spitting sound, that's driving me bananas. It's making the amp unusable for gigs. The preamp and poweramp clip LED's both light up. I've changed the tube, and gonna over the input jacks again with a soldering iron, but it happens completely at random. Has anyone ran into anything like this? It happens when Im not playing, too, so it's not just a silly clipping issue. Did I hear correctly that the enhancer level might have something to do with it? the reason I ask for help on here is Im in Ireland, there's only one relible amp guy around but he's not great on bass amps and he costs an absolute fortune. Any help at all would be greatly appreciated. thanks!
