My latests bargain purchase

[mentalextra]

I saw this old Yamaha rbx200 bass advertised and couldnt resist. Seller owned it from new. Hardly any use. One of the knobs has siezed and twisted breaking off some wires. Other than that all good. The action is a mile high, the neck needs a tweek and a new set of strings would be nice. I have a reason to hide away over Christmas now.

Does anyone have a wiring diagram that I could just take a peep at. As the bass only has two knobs I am guessing volume and tone, nothing fancy in there. It Looks to me like the "hot+" wire has come off the jack socket and an earth has been pulled off the siezed pot where it has "spun". But for my own sake I wold like to confirm that all is as it should be.

Thanks and Merry Christmas
