Free to good home for postage cost, a Heathkit PT-15 enlarging timer. Very old school electronics, no circuit boards in sight, all point-to-point wiring (in one color!), this baby even has a vacuum tube! Outwardly in good cosmetic condition, but it does not function.
I found a surprising amount of information including a partial manual and a schematic on line. But, I don't have the inclination or time to try and figure out its faults. If nothing else, it will provide a number of probably useful parts and a nice aluminum enclosure. It operates (or would, if it worked) on 120v AC, but I'm willing to post it anywhere on the planet you like.
I can post up pictures, but it looks pretty much like any other electronic timer, no display, just switches, two rotary switches for selecting preset times and others for setting the time intervals, switching the enlarger, etc. + outlets for enlarger and safelight. Refreshingly, the enclosure is two-tone blue rather than "putty", and metal instead of plastic
PM if interested, thanks.
