Thanks to all for the well wishes.
I can hear better today, but the ringing's still there... of course, as a former punker, I've got tinnitus from before, so I know what to expect. Yay rah. :|
Took the regulator apart (the operating rod) and installed a handle, as well as two functioning gauges from another regulator that was pulled OOS due to cracks in the body. Have recommended replacing the whole unit.
The regulator was functioning fine - it's just some idjit had cranked on it up to a bazillion Psi. It's now down to a more reasonable 150 Psi.
If I could install a limit pin I would...
