Durst M605 Help

Griffin Miller · Dec 9, 2020

Hey there!

I recently picked up a Durst M605 Color from a friend and was messing around with it a little before assembling it. I essentially got it new in the box, so some things were a little stiff so I was trying to figure out how to loosen the focusing mechanism. In the manual, on the 10th page, it mentions a screw underneath the friction drive and mentions loosening it to adjust the amount of friction it has. Only problem is a loosened it a little too much and the screw ended up falling out along with two other pieces. I'm not quite sure where the two other pieces go, so if anyone out there has an M605 and could send me a photo of their focusing mechanism, that would be great!

The slot goes up, and left, the bottom goes behind the ridge in the body casting and the protruding pin goes toward the shaft, In looking at my pictures, I'm not precisely sure where the felt pad goes, I think it must go under the pin. My enlarger is a M-601, but the mechanism looks the same. I hope this helps. BTW, mine has a color head, so has a cover where the lamp goes on a B&W unit.

I can make additional pics if you need.

Got it! Thanks a ton! This was puzzling me all day.

Running into another problem now. The copy of the enlarger I have must have been meant for the EU, or possibly they're all like this, but the transformer (Durst Tra 305) requires a 220-volt input. It's also got the standard 2 prong EU plug on it. I've done a little research and found that there are 110 to 220-volt step-up transformers that are readily available, but then that brings up another issue – my timer, which is only rated for 120 volts. I think the logical way to set this up would be step-up transformer plugged into the wall, timer plugged into the step-up transformer, and then durst enlarger/transformer plugged into the timer. This wouldn't work because then the timer would be receiving 220 volts though it's only rated for 120. Since the timer is only rated for 120 volts, I'm thinking I could plug the timer into the wall, then plug the step-up transformer into the timer, and then plug the durst transformer/enlarger into the step-up transformer. This would result in the timer getting 110 volts from the outlet, the step-up transformer would get 110 volts and turn it into 220 volts, allowing the enlarger transformer to get 220 volts. The only thing I'm concerned about is multiple transformers being turned on and off every time I make an exposure. I don't know a ton about this stuff, so sorry if I'm using improper language, but I figured this would be an okay place to ask. Let me know if anyone has any suggestions.

Yes, that's it.

Yeah, I see your point, but I'd just give it a go. Indeed the inrush current of the step-up transformer may be higher than that of the Durst transformer and that may wear out the relay contacts in your timer a bit quicker, but there's a good chance you won't live long enough to notice it. In other words, give it a try.

I own a M670 color, which uses a dichroic lamp inside the head. The lamp is 12V so the power supply is 12V (dc or ac). It came without transformer so i used a 220 to 12v transformer (i use 220v at my household) and it works fine.

If that's the case you can just use a 110 to 12v transformer, which is pretty common on electronics stores.

PS: I see my enlarger uses the same transformer as yours, so there's a high change it operates on 12v too.
