Hey guys,
I am getting a lot of hissing and crakling through my combo. So, instead of running it into the combo speaker I ran it through a Marshall 4x12 1960A cab and it went away. COuld this problem come from the transition wire between the amp and the speakers or just the speakers. If anyone can help that would be great
AD30TC combo ???

It's more likely that you have a bad tube that's crakling when it gets vibrated from the amp being cranked up. When you disconnect the internal speakers and play it through a 4x12 that the amp isn't touching, the tube isn't vibrating anywhere near as much, thus the crackling goes away.
It's also possible that the crackling could be a bad solder joint, or a bad component...but usually not the case in a newer amp.

If it was unchanged with a change of pre amp valves I'd suspect the power valves next. You could check for this by warming the amp up and <i>gently</i> tapping each tube with a pencil or wooden chop stick to see if you can provoke the problem. If one or more tubes cause crackles then you'll know what's up. If so, I'd ideally replace the lot.
