We recently purchased a horde of old
Altman instruments - 360Q's, fresnels, and some kind of
radial ERS's. Other folks used them during October for our Nightmare outreach, and now I'm about to get my grubby hands on them to add into our main sanctuary. I've read here on CB about what's called a "bench focus", but I'm not sure what all this entails. I'm supposing this would align the lamp properly? How do I go about this?
I've never really given any instruments a thorough going-over, other than re-wiring a few
PAR cans. I'd like to do a good job with these new tools, as I don't know the history of them, and I'll be hanging them over the heads of people I care about.
What else should be covered besides aligning the lamp? What type of cleaning should I do? What can I ignore? I'm certain there's enough instruments for me to choose from that I can pass over anything that'd be out of my league, though I am desiring to expand my knowledge of these things and learn some new skills. I fully intend to ignore the radials, as I know the 360Q's should outclass them, and we'll have plenty to go around.
Along the same line, what is the proper long-life lamp for a 360Q? Nothing high-dollar, not the high-output version. We've apparently been using some type of 1kW lamp, and I know that's not right.
If I end up needing parts, what's a good source? I know I already need a couple of sockets for some other 360Q's.
Thanks for your help and patience!
