Is it worth fixing my clear audio concept

sandstone, thanks that is what I thought but not that familiar with this specific arm. My great preference is for arms like this with continuous phono leads. The cartridge signal is exceedingly faint and the worst thing you can do is run it through a bunch of connections. Hard wired phono leads like this one are a lot better. This is the kind of thing where an accident repair can easily turn into a worthy upgrade. Far better to put a couple hundred into repairing and upgrading this wire than trying to buy a whole new turntable. Especially since this table will get you next to nothing in this condition. So it really needs to be fixed either way. Might as well do it right and have a better table in the end.

Only you know how much you liked the table, so only you know what it would be worth. Also only you know what "fork" and "ripped out" means. Every time one of these comes along it always turns out there's a bazillion critical little bits of information we learn only much later. 

Could be all's needed is solder the spade lug back on the ground wire and crimp a new cartridge clip and back in business. Or could be the arm can only be re-wired. Either way totally worth it on a table like that- IF you like the table. In reality the way these things usually go the guy just wants to upgrade and this is all story time. 

Which will it be? Wait and see.....
