I would have jumped on it, but all I can do is offer late congrats on everything, and if it helps any, I had 1, and have seen a few before closing our used/vintage shop, and there seems to be a few different models of connections for them, and have seen and still have the wire harness, and Jensen Alnico mid/tweeter pulled from 1 years ago. don't know if that was stock or not. but I seem to remember a few had dual 1/4" female connectors(like a steel, or plastic cased cigar) attached to one of the 1/4" males to facilitate hooking up a combo's supplied speaker(s), and a friend now has one with what appears to be a factory supplied cable similar to yours, but one of the 1/4'' jacks IS a female. I added a 1/4'' input jack, on an ''L'' plate in the little cord hole, and wired it straight to the multi pin so I could just plug in that way. worked great, and looked almost stock. Loved it, got many years of gigging out of it, and occasionally had 2 of em, (a buddies, on loan), and taking advantage of a house gig type of thing where we didn't have to strike our gear,(wouldn't want to move TWO of those suckers plus SR & 1959SL & 2x12 every night!) WHEW!. oh yeah, we had two clean ones at the store for a year or two, and no interest, then boom, they were popular again...the Beatles, Badfinger, Stevie Ray, Joe Walsh,...so many records you can hear them on, and I haven't heard a simulator nail it yet
