    I picked up a Laborator 1000 last weekend. Not bad condition plus it came with a 80mm componon and a RR Beard easel (scruffy but usable) all for the princely sum of 20 pounds!
    There are two pieces missing. The easily identifiable piece is the top of the lamp housing which I can get a part made for. There is one part missing on the condenser housing which looked like a thin panel held in by two screws. Behind this panel is a slot, well actually two. I would assume these slots are for VC filters. One is directly in front of the lamp housing the other at an angle. Could anyone confirm what these are for as I would dearly love to get this old gal up and running.

    Thanks

    I am not familiar with the 1000 but on my Durst 138S there is a slot for a heat absorbing glass, UV filter, and VC filters (on mine these mount into a holder). This is located immediately in front of the lamp. The inclined mounting I am not sure about. Could it be where the mirror is mounted? On my enlarger the lamp shines on a mirror and the mirror then reflects the light down through the condensors.

    That's right. There is one slot in front of the hole connected to the lamp housing. At the opposite end is the mirror that reflects the light through the condenser, and a slot at an angle just in front of the first slot. Do you have to use heat absorbing glass in front of the filters? I could just get a panel made to cover the slot and use the main slot (in front of the housing for the filters and glass if required).
    Slightly OT I have the chance to get a 138S at a very reasonable price and within a few miles of where I live, so it's easy to collect. What should I be looking out for before I buy? e.g. what potentially could be missing that is very hard/expensive to replace.

    thanks

    The filters that came with my enlarger are mounted in glass (acetate filter enclosed with two panes of glass that are taped on the edges). I mount my filters behind the heat absorbing glass. The heat absorbing glass in this configuration amounts to more "mass" to absorb heat. In your case if you are using filters that are conventional and not mounted in glass then I would mount heat absorbing glass directly in front of the lamp and then mount the filters in front of the glass. In order to keep costs down, I would probably use 1/4 in plate glass as heat absorbing glass. The light at this point is still "mixed" in orientation. It is only after it passes through the condensors that it becomes collimated.

    Regarding the 138S, I would want to have all condensors. That would be two each 240s, one 200, one 160, and one 85 (depending on the lens(s) that you are wanting to use. If it comes with lenses so much the better. I would want the lens panels to mount into the turret. I would check to see that the table moves freely (up and down). That it moves freely when tilting. I would check that the head moves up and down freely and the same for the head focusing adjustment as well as the head tilt. I would check to see that the column isn't scarred from some previous owner attempting to adjust the head height with the locking screws screwed down. Check the head and table mount for "play" in the bearings. If it were me I would want the variable contrast filters. However these can be fashioned if not available. By way of price comparison, a 138S was bid to $560 US this week and did not sell because of reserve. That enlarger had only two condensors. I bought a 240 condensor this week on Ebay. Cost was $92.00. Cost of a remanufactured Durst 138 S from Jensen Optical (US distributor) is $5,300.00

    The costly things about the 138S are condensors. And lamp conversion. The opal lamps are no longer available. Durst Pro USA has come up with a 1200 watt halogen conversion...cost is about $900.

    This is, in my opinion, the premiere 5X7 enlarger today. My condensor enlarged prints have more sharpness, more local contrast, and better tonal representation then my diffusion enlarged prints.

    Thanks for your help. These are my first posts on APUG, and the wealth of information and experience on this site is simply amazing.

    As for the 138S, if I can get it cheap enough (and I mean cheap) I will buy it for spares if it is not complete, then carry on looking for a nicer unit.

    Finally, coming back to the L1000 I will try the local Durst spares shop http://www.northernphoto.co.uk (a great source for older spares) to see if they have the glass mounted filters otherwise I'll just jerryrig something up as I really want to try a condenser enlarger on B&W.

    I found out that it takes an optional filter drawer called the TAUFIL (in Northern England that would wierdly translate to "that's awful!) and they are still available new in the UK. Not bad for a 40+ year old enlarger.
    So many drummers, so little time.
