xilddx Posted July 15, 2009 Share Posted July 15, 2009 (edited) The guy who owns it is my oldest mate and is a leccy engineer. He reckons a failing valve is making another run hot. He also thinks some of the components like caps and resistors may need replacing as it's a bit noisy. He knows a fair bit about valves and related electronics but doesn't want to tackle this himself. So, can anyone recommend someone good nearish London who could fix it? He also wants to know how much it might be worth to gauge how much to spend getting it fixed. Thanks as always, Nigel Edited July 15, 2009 by silddx Quote Link to comment Share on other sites More sharing options...

Apparently the valves are not running at full power. He knows a fair bit about valves but can't fully figure this one out. So, can anyone recommend someone good nearish London who could fix it? Thanks as always, Nigel[/quote] I know a very good valve amp guy, but he's in Brum, so I guess too far. Quote Link to comment Share on other sites More sharing options...

He recently revalved my Ampeg V4BH. PM me if you want his contact info. Quote Link to comment Share on other sites More sharing options...

Thanks as always, Nigel[/quote] hi if one side isn't getting the right bias and the other sides running hotter i'd recomend you take it to a tech asap, because in my experience that can get very costly if you let it keep on running like that Quote Link to comment Share on other sites More sharing options...

He definitely reckons the bias is out. He doesn't fire it up very often because of potential damage, he has a Hartke too. Quote Link to comment Share on other sites More sharing options...

I spoke to him last night and he would prefer somone close to London as he is not planning to go back to Cov for a bit. Thanks anyway, really appreciate it.
