I've got an ancient, and very battered, Level 12 that has just developed a problem. I don't really want to spend anything on repairing it as it's about to be replaced, but I'm wondering if there is an obvious cause for this problem that may be a, easy to fix myself, or b, just caused by my stupidity over looking the obvious.
Basicall the preset masters have no effect and both presets seem to be stuck at about 80%, the flash buttons cause the level of that preset to raise a bit so I know its less than 100%.
Any ideas?
