Peavey Delta Blues Tube, sound only w/ ext. Cab

Peavey Delta Blues Tube amp 1x15 makes no sound but works with ext. Cab 4x12 , Also the internal speaker works when the ext. cab is plugged in

I've never had a Dealta Blues on my bench so all I have to go by is the schematic, but it appears to me that there is a multipin connector interface that connects the output transformers secondary to the Internald and External speaker jacks and those jacks have switches engaged when plugged in. All of those need to be checked - The OT for any open windings, internal or simply a bad connection; the quality of both soldered and mechanical connections at the multi pin interface connector; and whether or not the switches built into the speaker jacks are working properly or not..

It should be an easy fix for anyone with a multimeter and a bit of circuit knowledge..
