When I wiggle the cable at all, I get speaker destroyingly loud pops and volume jumps. I looked under the hood and saw that unfortunately the jack is right on the board. Anybody ever replace this with a floating jack, in other words, a different jack connected with wire? Is this something not reccomended? I may just have a qualified tech do it, but I am handy with the soldering iron so if I can get some advice I'll give it a whack. thanks in advance for any thoughts on the matter.
