I am the M.E. at a summer theater, got here a few weeks ago and it was a complete disaster! All is well now, but I have some questions. It's been several years since I've seen any old altman instruments. After organizing all the lamps, I noticed that the EHG, EGG, and FEL's all looked nearly identical, and when I started replacing lamps in the altman 6x9, 6x12, and 6x16, there is NO consistancy! This may be a rediculous question, but are these lamps the same? (they were all the same wattage at least). Or was someone putting the wrong lamps in those instruments before I got here? The instruments are VERY old, but I'm about to go searching online for info on them anyways... Just thought some of you may know! Thanks!
