Hi, I am still trying to fix my Devere 108S. I called KHB Photografix today and ordered a manual. The manual does not include a wiring diagram, according to the salesperson (who was pretty rude over the phone for whatever reason, and seemed very impatient). He said that each of these enlargers was wired differently! This surprises me, and considering what a bad mood he seemed to be in, I'm not sure it's true.
Wondering if anybody knows if it's true that each of these enlargers was assembled differently, and/or if it's possible to get a wiring diagram for the person who is helping me repair it.
(I ordered the missing fuse holder from radio shack and it should come in a few days. It's possible that will fix the problem, but I sort of doubt it, since it looked as if that fuse had been gone for a while.)

Darkroom Automation's support web site has a file to help determine the required exposure correction for magnification changes. The ruler measures square-law light fall-off in stops. Simple subtraction of the new and old measurements yields the required exposure correction - no dividing, no squaring, no logarithms. http://www.darkroomautomation.com/support/stopsruler.pdf If great accuracy is needed then an exposure meter should be used. Different enlargers require different corrections for the non-square-law light fall off from the condenser or diffuser to the lens - this is only critical at small magnifications. -- Nicholas O.
