I've had a few of these projectors over the past couple of decades but I rarely had to change out the exciter bulb. Mostly played magnetic sound prints. But I recently got an optical sound print and need to change out the bulb. I cannot figure out how to turn it loose! It seems locked in. Is there a secret to this? I remember on 16mm projectors just pushing it down and twisting but this isn't budging. I know on the ST model I have it has a little lever underneath to push up and release the bulb. Help anyone? I would love to watch this film with a new optical sound bulb.

Enjoy the film! As an addition to this series of posts, who happens to have additional Exciter lamps for replacement? -
Hey Osi! Thanks for the film. Still hoping for a suggestion in getting that old bulb out of there without damaging something. It just won’t budge. I replaced many exciter bulbs on Elmo 16mm in the past and it was easy.Comment

Look at page 52 to change the lamp.
It just turns without pushing down. It uses a BRS lamp.

Mark, Try using a rubber glove or something similar to grip the bulb while pushing down slightly and turning counter clockwise to remove. I recently removed mine to replace some other parts and I know that it (the lamp) could be stubborn.Comment

Thanks for the tips. I have now tried 2 different BRS bulbs thinking the one I replaced was burnt out. It looks fine, there is a problem with the exciter getting power from the projector I guess. Is there a fuse anywhere for this bulb? I guess I'll have to dig out my old (and not as bright of a projection bulb or lens) ST-1200 to watch this optical film.Comment

Is the centre contact nice and clean? It's possible that the lamp holder may need some attention. Have you got a meter to check?
Perhaps the service manual might be able to help.
