I need to replace a broken speaker binding post from my QSC Powerlight 6.0 PFC amplifier. It is the black negative post that broke off. I attempted to weld it back together but that was unsuccessful.
The service manual describes the part and part number.
CO-000146-00 BINDING POST, SINGLE, 1 POS, FEMALE, 60A BLACK
I am asking here because QSC parts said this item is discontinued and out of stock.
I have been unable to find a suitable retrofit. So I'll need to get spares from a donor unit most likely.

Whoops, not much metal left after they drilled that hole - and the residual stresses probably started a fatigue crack. That amp seems to max at 3500W/2ohms, ie about 41Arms, so perhaps a 40A terminal post might be more suitable?
Well its probably a matter of time before one fails again - unless you can find beefier terminals that fit the space. Brass is not exactly a high-tensile alloy.
The only way to get 6AWG into such a post diameter is with an oval hole I suspect - perhaps a lower rated post of the same thickness could be milled-out to take thicker wire without compromizing the structural integrity so much?
Alas at these high current levels a steel post will produce measurable magnetic distortion, even if it might be stronger...

Long story, but after contacting QSC, I was able to get the OEM part number and contact Cliff UK, who identified the correct part and agreed to send me one overnight.
