James Broonbreed Posted September 17, 2015 Report Share Posted September 17, 2015 Ahoy, I've just switched on my amp for the first time in probably a few months and the valves are goosed - warbly, in 'n' ooty etc. Is it normal for valves to deteriorate in such a way? They were absolutely fine last time I used the amp. I've just got some new JJ's for good measure. Quote Link to comment Share on other sites More sharing options...
