    Hi All, I have rescently got a Durst 138S enlarger complete with two mains power supplies. One working the other not (as a spare for repair) The prvious owner told me that the psu's quite often gave trouble and need to be repaired. I haven't investigated any further than checking the fuse in the back of the unit.

    a) Is there a 'stock fault' with these units?

    b) Does anyone have a cctt diagram please?

    Thanks Dave

    You may be able to get that from www.durst.it They don't list the service manuals and schematics in the online shop, but I believe they may be available if you inquire.

    The working one is a EST 301 and the faulty one is a TRA 301.

    Cheers Dave
