i have the hd 147 head. my input jack causes me to loose solid clean connection. i wiggle it and i lose full tone or if i spray it with cleaner it will give me full tone for a bit. i want to replace the mini circuit input jack board but i cant seem to find this part anywhere? help!!!! ive inspected the soldering and it hasnt broken at all. i made a ticket with line 6 and they say that part is obsolete! what other alternative can work from other jacks from other line 6 amps? the spider?
