PSA: if you [accidentally] tighten the panel-mount nut too much on the binding posts, you'll find that the binding posts are actually two different pieces. The threaded part for the nut is actually a stud that is press-fit, not that strongly, into a rear-facing hole of the larger outer part of the binding post. So basically as you tighten the nut, you are pulling the stud out of the binding post, and at some point it just does the bad thing
I'm trying to weigh my options around:
1a) Press the stud back in and be very gentle with the nut
1b) Press the stud back in and solder the two pieces together
2) Ask Mr. BA nicely for a replacement which may or may not be free, and which might not be any better
3) Get rid of the binding posts altogether and do a homemade speakON solution
The part that bothers me the most is that there's a fine line (for me, too fine) between not enough tension to keep the right-angle tab secure, especially against a quick-disconnect terminal, and just enough tension that the whole thing fails.
I was only nosing around inside just to make sure everything was kosher, and I started wiggling the terminals around and of course I made one come loose. Not knowing that the binding post could be damaged by slight over-tightening... =\
