  • Bell and Howell Filmosound 185 no voltage to exciter lamp

    Very weird because the amp itself has been completely restored from the original schematic. The film movement part of this projector is flawless, but the exciter lamp will not fire and we've tried known good exciter lamps to no avail. So we put a multimeter on it and it's supposed to be getting 4V but it's reading zero.

    Does the rest of the amplifier still works? If ther's a mic. input socket then let's try it out. If it works fine then I'd suspect something simple (blown fuse/loose connection for example).
