    I use 250w bulbs on enlargers rated for 150 w , basically I go through more bulbs but I like the power.

    You really need to work with fresh paper, paper known to be fresh and not just bought yesterday. Todays papers have a life of 2 or 3 years. Time on the dealers shelf counts.

    Do not ever try to save diluted paper developer.

    Both of those conditions will give flat dull lifeless prints and no amount of manipulation will get the print you want.

    Grab some old negs and see how they work. Also get a bulbs with proper spectral coverage.

    I would guess the problem is with your "cheap halogen bulbs". Enlarger bulbs can be expensive but at least you know they are the right ones for the job. I once put a regualr bulb in mine and couldn't figure out where the big white area in the middle of the print was coming from--turned out to be the printing on the bulb denoting wattage and manufacturer.

    Thanks, Folks!

    I'm going to tear into the enlarger had today to take a look around.

    Incidently, it takes a 100 watt halogen, AND, I had trouble in the past with the bulb contacts arcing! I had to refurb the socket that the bulb plugs into, perhaps there's trouble there again! I don't notice any fluctuation during exposures, just REALLY dim....forgot to mention how tough it is to focus, even when opening up and dropping out the filtration. So thanks for thoughts around that subject, Pentaxuser.

    Steve, thanks; I have a primitive way of aligning using a level (done recently), but don't seem to suffer adverse effects in focus/coverage/exposure evenness.

    Bob, thanks for the thoughtful lengthy reply. I close the darkroom door and usually only have two to four negs to attempt. This is based on the roll's contact sheet, as well as eyeballing the neg on a lightbox. It just seems that my changes in density and contrast aren't anywhere near what I expected to receive. Your approach will be implemented, in part. Maybe it's all in my head (enlarger head, that is).

    I use fresh chemistry during every session, keep my paper inventory frozen (but none of it was received from Freestyle more than two years ago). Cheap stuff, but I've gotten outstanding results with it in the past. I have 1 developer and two paper types (1 FB, 1RC). As standard as I can make things, 'cause that's the way I ALWAYS done it......and it worked before.

    Thanks for taking the time to reply, folks. I'll check in again after dismantling the enlarger head....OH, an Agfa B66....pita to get at the bulb.

    Well, That Could be Some of the Problem!

    Found a cracked porcelain bulb receptacle, a cracked relector on the bulb, burned contacts inside the porcelain, and a blackened portion of the halogen lamp itself....maybe I don't suck as badly as I thought!

    Now to rig it up again

    Sounds like a Dichro head -

    I think this enlarger takes 12V bulbs, you don't have 24V bulbs in by mistake? Is the power supply delivering 12V?

    Is the filter mechanism working - has a filter dropped and stuck in place? Does the head have an ND filter that may have gotten stuck?

    Praise the Lord ....

    And pass the electronic parts. Now to the web to find replacement porcelain sockets.

    Yep, Nicholas, it's a 12v deal, all else looks good, Thanks!

    I used it in the last four printing sessions, before I went mad....mad, frothing at the mouth, mad I tell you Steve!

    Jo,I hope you have success in your search but if not then you might try cleaning the two prongs on the bulb and the inside of the porcelain holder( the female end) can be cleaned with a small jeweller's round file or in the last resort with some wire-wool wrapped around a thick sewing needle. Well it worked in my Durst 605.
