Thanks for the input. I might give the drill-out a try. I should be able to carefully drill the hole all the way through and get a suitable screw and nut through it. There are some even smaller ones than 4-40 if need be. I also have some needle files I bought from Brookstone years ago and a small round file might be just the thing to use if the hole is just a bit too snug for readily available machine screws. I think the screw head would likely be best on the mating side and the nut on the backside.

I think I will keep the original socket because if the speaker ever has to be replaced with a similar field core speaker, it will be best to just be able to plug it in rather than having to change wiring. The OEM wires were cloth covered but were quite brittle and due to all the handling I put the chassis through while removing top-side components, cleaning and painting the insulation on the speaker wires broke open.

I plan to put a plastic sleeve inside the cabinet similar to those that can be placed in loose leaf binders. I will indeed include information on any circuit changes that I may make. I plan to keep things as near to original as I can within economic reason. If I make a change to an alternate wire color (as I have already done in a few cases) I will make a note on a copy of the schematic and include that.
