Dandelion Posted March 8, 2014 Share Posted March 8, 2014 Should I have a spare in case of failure whilst gigging? Or does failure hardly ever happen? Ta! Quote Link to comment Share on other sites More sharing options...
gary mac Posted March 8, 2014 Share Posted March 8, 2014 You've got me worrying now Mine has been very reliable to date but after four or five years of regular gigging, I think I should get a spare valve. Mind you, I do carry a spare amp, so it's not too much of a worry. Quote Link to comment Share on other sites More sharing options...
Dandelion Posted March 8, 2014 Author Share Posted March 8, 2014 Mine keeps plodding on too. But as the shuttle is single channel I presume that preamp valve failure would result in no output. Would this also be correct? Quote Link to comment Share on other sites More sharing options...
Dandelion Posted March 8, 2014 Author Share Posted March 8, 2014 Or would it failsafe to Mosfet? Quote Link to comment Share on other sites More sharing options...
MOSCOWBASS Posted March 9, 2014 Share Posted March 9, 2014 I keep a spare valve just in case, but have had no issues in 5 years. I also keep an Agie tone hammer handy just in case....paranoia or good sense? Quote Link to comment Share on other sites More sharing options...
Ghost_Bass Posted March 10, 2014 Share Posted March 10, 2014 If you need to replace the valve mid-gig mind that that task will take you some considerable time. There are a lot os screws if the way of the valve. Thing is, a valve could fail any time, just a knock would make it unuseable but they normally fade away with time, a lot of time. If you give proper maintenance to your amp and replace the valve regularly (each two years i would say...) it will never fail on you. If you are infortunate to see it fail during a gig then the best thing is to have a DI pedal at hand and send the DI to FOH and the line out to the FX return on the shuttle. It will be easier an a lot quicker to solve the problem. Quote Link to comment Share on other sites More sharing options...
Merton Posted March 10, 2014 Share Posted March 10, 2014 It's a preamp valve. Very unlikely to fail I would have thought, unless it was faulty to begin with? Quote Link to comment Share on other sites More sharing options...

I think that mid-gig is very unlikely for it to fail. Quote Link to comment Share on other sites More sharing options...
