Hello Everyone, I have a weird problem with my new Saunders 4500 II. I just installed it (wall mount) and went to make my first contacts with it (APO Rodagon 80mm wide open) and noticed that I had serious uneven light fall-off on the resulting 8x10 prints. Half the print was darker than the other half. I checked the diffuser box, but I could not figure out where this light fall-off was coming from. After some time, I discovered that if I stopped down the lens to f8 the fall-off went away, but this is weird. Something is not right. When I took the diffusion box out again for inspection, I noticed that the hole on the side of the enlarger head (that lets the light in from the lamp house) was misaligned with the module filter hole by about a quarter inch. I assume that Saunders designed these to line-up evenly. I tried to push the module as far in as possible to get the 2 holes to line-up but I couldn't do it. It seems to me that the origin of this uneven light has to do with this misalignment between filter module and enlarger head. Does anyone out there know how I can adjust the alignment of the filter module and the enlarger head? Oh and one more thing: The lamp in the head is 200 watts but I am finding it too low for my purposes. Having to do an 80 second exposure at f8 for a simple 8x10 is way too long. Is it possible to up the wattage of this bulb. Thanks.
