Hi All, Hope you can help me as i have a problem: It looks as though I've put DC into the input of my Little dot MkII. (While modding a CD player) The volume control went scratchy and now it's down lowish on the left channel and very low on the right. They both equalise if I turn the volume up to max but it's still low. I assume I've fried the volume control but what else should I look at or should I leave it to a pro to fix?
