Thanks for your reply. Here are the pics. Any help would be great. By the way the (grey wires) are for the bypass of the power amp and are switched via an on/off switch mounted to the original fuse location. The speakers are wired to the leads as originally made by ampeg and then a wire is run to the switch to run the cab as speakers only.
In this pic you may be able to see that the black lead from the power cable is attached in the orange twist cap with a lead from the fuse and a lead from the power switch. The white lead is soldered to the post and the other end of the post has a lead from the light (which doesn't light up) a lead directly from the transformer and a lead from the power switch. The solder looks old and factory soldered. Yet I believe the fuse assembly has been changed as the original should be flush mount to the panel?
Here is a closeup of the wiring from the fuse end and the transformer and light. Not sure if this is factory but it is not indicating any power.
