    Are the dichroic filters dirty?

    You got it NEW a year ago? What are these thing going for, $2500? I'd try to get it repaired under warranty (should be 5 years).

    No, they look clean.

    I bought it as new old stock. I got a hell of a deal off of ebay. So there's no warranty. It was brand new out of the box. I'm hoping it's just the bulb. If I have to replace the bulb once a year so be it. I'm extremely happy with the enlarger otherwise.

    Is magenta supposed to fade as the bulb is losing spectrum? Thanks.

    I'm a little worried it is not the bulb, usually those bulbs go suddenly. Nothing wrong with checking with a new bulb, you can alway use a second spare bulb.

    If you have a way to measure AC voltage you can check the terminals with a bulb in place and the lamp on and see if you get 82.0 V

    If not, then something is amiss. The first place to check would be contacts, like any connectors or the bulb socket itself. Something could easily get corroded during storage, even on new equipment.

    I did try plugging in and un-plugging the bulb quite a few times to see if I could clean the contacts. When measuring the light intensity before and after this did not do anything. Replacing the bulb will be the first step and if that is not the case then I can go from there. Let's hope it doesn't get to that point.

    Fixed my magenta weakening issue. The light bulb was not centered.

    Just to update everyone, I got the new bulb today and that's what it was. I measured the light wide open at grade 2 with a Darkroom Automation enlarging meter at a certain height with the old bulb and got a measurement of 3.4. As soon as I put the new bulb in and turned it on I could tell a huge difference. The meter now measured 6.8, twice as much light!! I'm happy that this was the problem. Now I need to write that measurement down and remember to check it several months from now.
