Pink's photos

A projection lamp?  Carbon arc?

Ding! we have a winner, or close enough.

Old-school follow-spot on a gimbal. About 10 foot long, 24" (?) parabolic mirror. Power supply output specs to the carbon rods are 55-65 VDC, at 105-115 amps.

There are four of these still in use at the local arena.

With the access door securely closed, and if you ignore the obnoxious reflection of my camera and fingers, this is the follow spot fired up through the green welding glass window, at near the same angle as the other pics.

Is it time to replace this fader, or does it still have plenty of life left in it?

..naa, you just shift the 2x4 contact brushes a tad upwards, and the fader is good for at least 10 more years..

;D

In the lean days, I've done exactly that to get something back in service until new parts showed up.


And for today's Red Plate Special:

Sylvania 6550, well done.

You see, this is why I prefer my tubes medium rare!
