I've been looking into ways to rehab approx. 20 Altman 75Q's. Currently, half are operational. Half are wired for double-ended halongen T lamps, mostly the ones that are not in "working" order. Refer to the discussion on the Kliegl ERS's that used similar double-end lamps and to how much this idea sucks. The other half are wired for the more conventional 1,000 watt BVT lamps. While the thought crossed my mind that I could easily upgrade all to use BVT's, I can't help but wonder if there are better options than the BVT. What suggestions does the Booth have for lamping a 75Q?
