Hello there, I have a strange (at least in my opinion) case with a 412 cabinet that a friend actually gave to me together with his JMP head because he doesnt have the energy to bother with garbage that doesnt work... His loss I suppose.

Anyway, the cabinet is a 8412 with 4 8 ohm Celestion G12L speakers, and for some reason just two of them work.

I tried the 9v battry check, and they all popped, and I followed the link above to that helpful site with wiring for dummies like me, and as far as I can see the cab is set up in series/parallell combination. The wires look completely ok as far as I can see, but just the same, the upper two speakers are dead.

I should mention too that the input socket has suffered some beating and is fixed with some of that ole duck tape.

Anyone got a clue?
