    Laser Warning Melles Griot Omnichrome Series 74 HeCd Helium Cadmium high voltage coil

    Hello

    I was wondering if someone may have a used high voltage module that mounts at the rear above the HR onto a bracket to the sidewall of the head. Mine has developed a crack and needs replacing. I will post a picture of what it looks like.

    I have a damaged Omnichrome HeCd head which is the predecessor, I'll have a look.
    Right, is it yhe moulded assembly with the 4 pin socket and the EHT screw connector on the other end, about 120mm / 5" long?

    I took some pictures it sounds exactly what you have. If you do indeed have it and would be willing to part with it, let me know your price with shipping to USA Iowa 51503. I can pay yo by paypal if you have an account or arrange another payment option. I tried to seal it with rtv but no luck its internally defective. Thanks in advance and God bless my friend! 20171012_103542.jpg20171012_103534.jpg20171012_103546.jpg

    It's doesn't look quite like that, it might be the same electrical circuit but it probably wouldn't fit; I'll put a picture up shortly.

    It is smaller but has all the correct connector and most likely would work. Are you willing to sell it send me a price for postage included and I can pay you with pay pal or other option. I look forward in hearing from you. Let me know I'm in the USA zip 51503 IA.

    I think that is the ballast resistor; I have one in a head with a broken tube. I am in Tampa FL, USA, where are you? $25 for removing and packing etc. plus shipping. Phil
