    Never had a problem, however, did start using an electronic one for additional features.

    I own the GraLab 300 and 400. The 400 is the auto reset version, both are similar except for this function and maximum time set; 300=60 minutes, 400=60 seconds. The safelight off during exposure function works the same for both. Very accurate and reliable. One caution though: they don't work with voltage stabilization, therefore, not recommended for color printing which requires stabilized voltage to avoid color shifts caused by changing lamp color temperature, which occurs during current fluctuations when other appliances are working in the same circuit.

    I now use compensating timers for cold light printing and developer temperature change compensation.

    There's nothing wrong with that timer. I have one that's very old and it continues to work consistently and accurately. I've compared it against a quartz controlled electronic timer and they match.

    There are two switches on the timer. The switch at the top left is used for focusing the enlarger. Set it to "focus" and the safelights are switched off and the enlarger is switched on. The timer is out of the circuit. At the top right there is another switch. This one powers the timer. Switch it off to set the time. Safelights and enlarger lamp will be switched off. When you are ready to make the exposure, flip this switch on. The timer is now in the circuit. The enlarger will be on for the preset amount of time. The safelights will turn on automatically at the end of the exposure time.

    Thats what I do too, there is something nice about the old analog clock face and makes it easer to time the agitation cycle.

    I have a cold light and use a Zone VI compensating timer for my enlarger which works well for me. I will keep the Gralab for film developing.

    Paul Horowitz who modified the Pentax Spot Meters also developed/designed the Zone VI compensating enlarging timer as well as the Zone VI film/paper compensating developer timer. I own all three and never found a need for anything else that came along since the early 80's as they provide complete control of the entire manual process.

    My GraLab timers are still in service though; for timing a toning process, print washing, and dry mounting, among others.

    I don't mean to hijack the thread, but I have to ask - so the faint glow of light that this timer gives off when the room is dark does not negatively impact film development? (I'm speaking of development of LF film in trays)

    No. It's fine from a few feet away.

    I aspired to a Gralab 300 for years (this was pre-digital---back when that last wooly mammoth slide into the LaBrea tar pits) and finally got one several years ago. I love it! Its simple and so, I've been told, am I
