    i'm back folks, with bass amp problems!

    This time it's a carlsbro stingray probass from early 90's (i think!).

    It has a mains hum, (i've already replaced the caps, so thats not the problem), and i'm close to throwing it a good 3 meters or so in rage!

    The hum is probably an out issue as it's not effected by volume/eq control and occurs regardless of anything being plugged in, and when something is plugged in it works fine, just has this really loud overpowering MMMMMMMMMMMMMM, and when you turn the head off, it creates a visually loud pop on the cab speakers! (you see the speakers invert).

    HELPS.....
