Devere 5108 Power Supply Schematic

[Photographica]

For you do-it-yourselfers, I thought I'd post the schematic for my power supply. I have a Devere Dichro color head on my 5108 that I just acquired. I didn't get a control box with the system so being a retired engineer with a little time on my hands, I just sketched out the power supply schematic to figure out how to connect my Gralab timer as a controller. I couldn't find the schematic on-line anywhere so I thought it might be possible someone else might have use for the details.
Word of Caution: The power supply connects to Mains power so physically disconnect all power (that means unplug - don't just turn off switches) before you go digging around inside the box or probing connectors.

Finally, be sure you know what you're doing if you decide to make any modifications to the electrical system. Everything works off Mains voltage (110 Volts or 220 Volts). If you rewire something in error, you might let all the smoke out of your enlarger... or worse!

Cheers,
Bill

Thanks for posting. I added it to my collection of schematics.
How is the rest of the enlarger? How did you move it? Pictures???

The enlarger is great . I really like the counter balance action for raising and lowering all that weight. One note to anyone disassembling for shipping... Make sure you lock both the lens carriage and head platform before you unload the weight. The springs are powerfull.
I have the wall mount version which will make it easier to set up in a standard room. Height wise it's not much bigger than my 4x5 Chromega. I'm in the processes of re-building my darkroom benches to accommodate the addition of the new enlarger.
I was fortunate to get all the parts at an auction in Indianapolis recently. Everything was spread out and I had to get it with a total of five separate bids. Even at that, I got it at an amazingly low total price...
