    I just scored this enlarger with some lenses and the usual neg carriers etc. What a tank! I know nothing about Durst enlargers. Anything I should know about this one before I set it up?

    I got one a couple of months ago, with a condensor and cold light head (Taupoli?). Haven't had much of a chance to play with it yet. Mine came in five boxes, but it went together fairly easily. If you need a copy of the manual I'll copy it for you when I get home in a week or two.

    I've also got one that I'm fixing up. As you say built like a tank and very smooth mechanicals. It makes my modular 70 feel rather flimsy. I've got a rough copy of the manual in PDF format if you need it. The only thing to watch is to lock the head assembly before removing the colour unit. It ends to fly to the top and can do a bit of damage to the old fingers. I speak from very painful experience!

    I have a couple of the Durst L1000s, one a table mount & other a wall mount. They both have older versions of color heads (Pavelle 401 & Mark II 410). Do have the L1000 manual & could scan/put it up on my website if anybody needs it.

    I have a Durst L1000 with a CLS450 head - a nice solid machine. As previously mentioned, lock the head assembly before removal although in my case the spring is on the weak side - at some stage in the future I need to add a counter balance as it's significantly easier to lower the head than it is to raise it. I had to partially dismantle the head to clean it and also to lubricate the mechanism which temporarily moves the filters out of the light path as it would occasionally stick - nothing complicated and applicable to nearly all enlargers which have been sitting around for a few years. Apart from the spring it's probably as good as it was when new - they're built like a tank and the only thing that might cause future problems is the power supply.

    A manual would be very nice. Also how do you lock the head? I too have had my fingers bitten.

    Another version of the Durst L1000 Manual Hope it helps for keeping the fingers safe.

    I've got an Otopfe 450 (4x5 carrier) for the Laborator 1000 if anyone needs one. It's the only remant of my 2 Durst L1000's... Cheers, Richard

    Hi Eric !
    I own one.
    Be carefull if dismantling the beast for cleaning.
    NEVER EVER OPEN THE ROUND SPRING BOX AT THE REAR of the column. It contains a thin metal spring sharp as a razor blade and prone to kick at you FAST. Terrible injury planned !!! To open it needs a set of special tools to release the tension before opening and a proper procedure not to be injured. So keep away.
    Also, if you open the head for cleaning avoid to project WD 40 or things like that into it. Every drop reaching a filter will permanently remove the thin metallic deposit making it a filter, and leave a spot, ruining it. It is becoming difficult to find new dichroic filters cut to size... I can tell...
    Double check the solder in the plug (both male and female) in the transformer. The lamp cables are large and stiff. During use, the cable put a heavy effort on the solders destroying some of them. So the current has to go from 4 pins to 3 maybe 2, causing spikes, and helping the bulb to die earlier, unexpectedly...Double check also the bulb socket. These have very small pins to hold the bulb, prone to oxydation, and getting loose. Go to the largest lighting/bulb store in your town, ask for Halogen bulb socket and buy the "professional" one rated at least 250W. (they often come with wires covered with Teflon insulation to resist high temperature, and may have very thin wires ). Its easy to replace and will give you better lamp life and more constant output. I tend to replace the socket at every lamp change. Some people often crimp wires to the bulb directly to avoid socket problems...
    Clean the fan's blades. The dust sticking to them cause bad balance inducing noise and vibration.
    Parts show on Ebay from time to time. Keep an eye open and watch.
    You will be pleased with your Durst, and will enjoy printing with it. It could be the last enlarger you buy !

    All, I just picked up one of these as well for cheap, but no color head though. Anyone have a CLS 450 head laying around not doing anything? In the manual that I have, it calls for the CLS 401 head. Is one better than the other? Can it use the CLS 500 head that I see on the 1200? Thank you in advance. I look forward to putting this thing together this weekend.

    I think you can use the CLS500 head on the L1000 with the right adaptor, but whether you can get the adaptor is another question.

    I think (and stand to be corrected) that the difference between the 500 and 450 is that the 500 has an ND filter included.

    The L1000 with CLS450 is my backup to my L1200 MG500.

    My L1000 is up against the wall with the Durst made wall mount. I only have the condenser head, but very complete with filter drawer, a heat absorbing glass between lamp house and mirror compartments and I installed a small fan into the lamp head, in the hole for the fan system Durst provided as an option. Also managed to find a supply of the large bulbs, Thorn and Atlas . . . these provide even illumination. For more than 35 years I have used Leitz enlargers and still do, but this Durst sits right next to them in terms of being one fantastic enlarger. I like its simplicity, non automatic focusing and metal build.

    Although your manual may indeed call it "CLS 401", I believe that the correct head name is "401" only. It's a bit of an hawkward design, with twin lamps acting from the left side, and an external forced air cooling fan that has to be connected to the head by means of a corrugated piping. Not really convenient and nice to look at perhaps, although it does the trick.

    The CLS 450 is a more evoluted head, single lamp, with self-contained automatic forced air cooling, and filter regulating rods that can be conventiently actuated in seated position or easily reached when the head is rised up to the top of the column. It also looks much better from a design standpoint, and I believe that for all these reasons it sold in much greater numbers (possibly also because it stayed on the market for many many years: when the Laborator 1200 replaced the Laborator 1000 it was still available, and as a matter of fact many Laborator 1200 units have a CLS 450 on top rather than the later CLS 500).

    I performed a quick search on eBay and I'm amazed by the fact that nothing seems to be available at present time. Durst Laborators and relative colour heads were top-of-the-top professional gear and were always difficult to find on the used market; however, I remember that when I could finally put my hands on one, right in the middle of (and thanks to) the digital madness, there was a bit of a choice, like 2-3 units to pick up from, in different conditions and prices. In any case, make sure that the head comes with its power supply unit or it will be useless.

    Was going to offer the same advice as above. I have two of these and they are excellent enlargers. But please DO NOT open the coiled spring at the back of the column. As above, serious injury is very likely to result. Lots of adjustments possible, and multiple heads are compatible.
