I recently purchased a second hand Orange Rocker 30 head, and PPC 212 Cabinet.
For the first month or so the amp worked fine and sounded excellent.
However... during a band practice my amp suddenly went quieter. Not so quiet that you cannot hear it, but quiet enough that it is drowned out by drums, and my friends 30w Vox when played at about a 3rd of full volume whilst mine is at full.
I recently had the valves replaced by a pair of 'Ruby Tubes' as suggested by my local Orange dealer. However unfortunately this has had no effect what so ever.
If anyone can suggest any way I can fix this loss of sound it would be much appreciated.
Cheers
Mat
