    Hi,

    Does anyone know if there is a repair/service manual or schematics for Beseler Dichro 45s head? I'm not talking about the user manual. I recently got a used 45s and want to keep it running as long as possible. If you happen to have a copy, could you please email me a copy?

    Thanks a lot in advance.

    OK guys so you got the manual n some pictures of the vactroll casuing the delayed light problem...

    How did it work out for you n what was the cure?

    If we can document this, then when people look it up, the fix is right here.

    I think I had the same problem. It's when you push the timer and there's a delay when the head turns on. I had to replace the optio isolator.

    i need more info on the opto isolator for the 45s. this lag is really infuriating. We checked how much current goes to the bulb and it's rated at 62 volts, but the case says 82volts. not sure if there's something else wrong with the board or if 62 is normal. as of now ive unplugged the 2 bulb cables to bypass it and hooked it up to a variac. but this is too bulky and unrealistic. i got an external box that i'm rigging a dimmer, bypass and timer switch. but i'd rather use my time-o-lite... so please provide a service manual, schematic or pics of the fix for probelmatic part, where i can get it etc.
    please and thank you!

    I have a dumb question. If the bulb is rated at 62 volts, then why would you need the xformer at all? Would not a good strong diode do?

    bulb and machine are labeled at 82 but the pc board puts out 62v
    maybe my board is screwed up

    Hello,

    New to forum and found this thread while looking for information on how to repair a Dichro 45 colorhead.
    Any chance I can get a copy of a service manual or schematics? On occasion, err is displayed on the filtration display.

    Thank you in advance.

    Mike

    I'm also looking for repair manual and/or schematics for non-computerized version of the 45s head. Anyone still has a copy?

    thanks
