Ok, so I bought an 810H De Vere enlarger a number of years ago. Last spring, I re-did the basement to accomodate it and installed it. This took months, as the floor was uneven, I had to build an alignable frame to hold the vacuum easel... And I had Tony at Lightwave in London craft me an adapter so that I could use my RH Designs Stop Clock Pro with the enlarger. So tonight I've finally got everything ready. The chemicals were mixed... I plugged in the RH timer and hit focus. Everything came on correctly, and so I focused the enlarger. Next, I changed the timer over to 'test strip' and went to get a piece of paper. When I got back to the enlarger, all of the lights on the Stop Clock were out. I checked the fuse and tried plugging the timer in elsewhere to no avail. Nuts! That was my favorite piece of darkroom equipment. This wasn't a very auspicious beginning for my 8x10 enlarging!
