I desperately need a TBP12 TA4f Input Jack - Line 6 50-02-5010 4-Pin Input Jack. I own a g30, a G50, and a G90. I've owned 2 G50's, and 2 G30's. I've replaced the defective battery doors on three. I have 5 transmitters. Only one still can hold the input cable in. I'm Always gentle. But it's a bad part. I really don't like taping things together. Can ANYONE locate 2-3 of these for me?
