Just aquired a 394 aluminum original for cheap and came across this thread of comments. First of all I had to buy replacement head and bulb which installed today. Been running at 18 volts with no problems yet, approximately 30 minutes. I don't like the cheap head because the color of the Fresnel lens isnt right compared to original but what I really question is the bulb itself. It just seems to me that the dimple on the bulb is too big to accept the delicate needle point of the housing correctly and would have problems getting centered and going. Figured I'd ask the post war guru guys about this but am refusing to use a fan for something that I feel will work?
