I mean the Banna plug speaker Binding post on the back of the TFM-6CB. One of the Red + plugs broke off, so I'm assuming I have to replace the entire bank of 8 which would probably be the easiest. I also have the Pre-amp CT-24, for the pre-out RCA connectors, the metal part of those two connectors are missing. So, all that's there are two plastic nubs that would be pointless to plug into since the metal is what transfers the sound. I'd post pictures but I can't do that, yet I guess.
