No it won't because he gets the roms along with it...
the sound rom can be replaced with a eprom anyway, that's a regular mask rom socket.
That's another story, then. Your earlier reply didn't specify it was the TK2 board along with the ROM. The way it sounds, though, it can be a minor fault, like that broken pin on my board. I'm not even sure how you can break a pin on that thing, because it's "protected" by the B board, but my TK2 is a proof that, apparently, you can.
Hopefully, an investigation of that ROM and its adapter board will reveal something easy to fix. I'd try burning a new ROM as well.
