bassjamm Posted December 17, 2009 Share Posted December 17, 2009 Hi everyone, I've just taken receipt of a Mesa Boogie Bottle Rocket pedal from a seller on ebay. Now I'm no genius when it comes to things like this, but am I right in thinking that valves have an orange glow about them when they're in good order, and that when they're gone, the silver top bit seems to be more cloudy? Thing is, the two 12AX7A's that are in there, well, one seems to look fine, the other doesn't. The dodgy looking one hasn't got a glow at all really I've had a good play about with it, but can't seem to hear any problems tonally. Am I doing something wrong? Or is the valve gone d'you reckon? In a darkened room, only one is visibly glowing! Thanks in advance for any help! Jamie Quote Link to comment Share on other sites More sharing options...
ahpook Posted December 17, 2009 Share Posted December 17, 2009 valves don't always glow - when i was swapping round valves in the dha pedal i had a while back, some would light up, some wouldn't. if it sounds ok, i wouldn't worry about it.

geoffbyrne Posted December 18, 2009 Share Posted December 18, 2009 (edited) Try swapping it for a European-built (NOS) ECC83 - & if it doesn't sound any better, leave it as it was. G. Edited December 18, 2009 by geoffbyrne Quote Link to comment Share on other sites More sharing options...

Jamie[/quote] if the silver on the top is beginning to fade away thats an indication the valve is on its way out, not all valves glow though especially if there being underrun Quote Link to comment Share on other sites More sharing options...
bassjamm Posted December 18, 2009 Author Share Posted December 18, 2009 I think it may be that the valve just doesn't glow then. There's no fading in the valve, nor any audible dodgyness!!! Quote Link to comment Share on other sites More sharing options...
carlitos71 Posted December 18, 2009 Share Posted December 18, 2009 have you tried swapping the valves? Quote Link to comment Share on other sites More sharing options...

But as has been pointed out earlier in this thread, it may not be a problem at all. I mean, it sounds fine, I just assumed both valves should glow?!?!
