Ampeg 4x10&1x15 fridge cab

[fiberglasslvr]

I have recently purchased this cabinet for a great price, but there is a problem with the crossover. the horn attenuator switch is broken off, so i need to replace that, so my question is where can i get a replacement rotary switch? or get a full replacement backplate for it.

any help with this is greatly appreciated and thanks in advance

Take a photo of the working side of the busted switch, and maybe we can help. I mean the part inside the cab where the wires connect.
