Hey CB, I'm usually so good when it comes to up keep of equipment but my shinning record was destroyed when a few of my Par16 Birdie fixtures came back to shop w/out their adjustment knobs. They were all completely removed from the yoke and not a single person on staff has any idea on the whos or whats of the situation. Anyway I've been searching for replacements and I just can not seem to find any. Does anyone here know of an online production supplier that keeps these tiny devils in stock? I've checked StageSpot and Production Advantage (my normal go tos)... Thanks CB, keep on keeping on!
