If anyone is interested - I have a ton of dual binding posts for sale. American made, double nut, flatwasher and lockwasher, mount in standard 3/4" spaced 1/2" holes, they take a banana plug, wire through the hole, spade lug, etc. Solder to the post or lug the back. Very nice. Two sets (4 pieces) for $ 10 shipped. Cash in the mail or PayPal.
