paul j h Posted April 26, 2014 Share Posted April 26, 2014 Hi All, I posted in another post about my amp having an annoying hum when using he drive control. After some great advice on the forum and from Guy at Ashdown amps I have bought a replacement valve for the preamp. But here is the problem, how do I get the thing opened to replace the valve? sorry if this is a silly question, but I have looked around and can't find any means to remove the metal casing to get to replace the valve.any advice?

deanovw Posted April 26, 2014 Share Posted April 26, 2014 On the top of the combo are screw covers. The little black circles. Pop them off to reveal screw head. Quote Link to comment Share on other sites More sharing options...
