    I have the exact same enlarger as you but with the reverse of your problem. I was used to using a very old Meopta Axomat 1a which gave me 8 seconds for 5x7 and around 20-40 seconds for 8x10 (20x25cm). Switching to the Durst, the 5x7s were lucky to need even 3 seconds and 8x10 were around 10. At any rate, I switched out the globe last week for a 75 watt globe which has slowed things down a tad.

    The M600 has a maximum ability to use 150 Watts, so it won't have any trouble if you want to up the wattage of the globe.

    Maybe the M600 is a totally different beast from the 605 which I have. When I did the old Agfa MCP( not the Adox one) at 20x25 cms using a dichroic head for dual filtration my times were nowhere near these. Probably not even as much as Molli's times. Probably around 20 secs max but more like mid teens and this was the 100W halogen bulb

    You are getting about 60 secs for a 20 x 25 which is not a big print and over 4 mins with the other paper. Seems incredible compared to my experience but if the prints look right then no issue. Your dodging and burning can be relaxed

    Very long paper exposure times

    Wow, I have times with my V35 @f5.6 and a VC module between 6 and 10 sec on Ilford MGIV fiber glossy 9,5 x12 inch. The lamp is the Philips 13139. Film is TRI-X developed in Rodinal 1+50.
    What could cause such a time difference ? Are you printing much bigger ? Smaller f-stop ?

    Burning was fun indeed. 1/2 stop = 32 secs.

    I know developer is not exhausted yet, since one print came really well after 2:30 mins which is normal for ECO 4812 developer.

    I will test again with fresh developer on coming weekend and see how it goes.

    Vario Classic seems slow paper @Grade 3 it is ISO 40 where as it is ISO 160 for MCC.

    Rolleicord Va: Humble.
    Holga 120GFN: Amazingly simple yet it produces outstanding negatives to print.

    As you are finding, it depends on the paper and chemicals.
    Some times you are stuck with the long exposure because of the paper, and there is really very little or nothing that you can do about it.

    On the M600 you can put in a 150 watt bulb, for more light. I use my M600 with a 75 watt bulb, because the 150 watt bulb is TOO bright, and results in very short exposure times. Then swap back the 75 watt bulb after you are done with the print using the 150 watt bulb. The smaller wattage also generates less heat.

    Enlarging lens: Schneider Kreuznach @f/8 50mm.

    Paper: MCP 312

    Without filter: Paper speed is ISO 400 require 20.2 sec(f-stop printing).

    With Grade 3 filter: Paper speed is ISO 160 require 64 sec(approximately).

    Paper: Adox Vario Classic

    With Grade 3 filter: Paper speed is ISO 40 require 256 sec(approximately).

    Filter was placed under the lens.

    Paper Developer: ECO 4812 Moersch.

    Question: Is it normal to have such a long exposure times for paper.
    I would suggest this neg is over exposed by at least 3 stops.

    I hadn't thought about this but it would certainly explain why the times are long. The key here is: are the negs really "meaty" looking and even if they are it depends on the OP's definition of this. If his negs have always been this way then my and your "meaty" is his normal.

    Maybe there is no way of getting to the "why" short of seeing the negs and even comparing them with yours and mine. Clive

    I know little about scanning but maybe a scan of the neg would help answer this?

    Very long paper exposure times

    Maybe 'overexposed' by some people's standards, but it could well be that OP gets exactly what they want this way.
    Many photographers rely on more exposure than box speed, as well as more developing time than recommended.
    Ralph Gibson comes to mind.
