You want to stay the same capacitance. You can go up in voltage, but higher voltage is usually equated with a physically larger device (at the same capacitance value). Going lower on the voltage can result in eversion of the capacitor... -j. -- Original message -- From

I have to say that the clock in my 300D is about the most accurate timepiece I own. I only adjust it for the start and end of daylight savings time, and in that interval it stays within 1 minute of the actual correct time. Before Indiana started observing DST, I basically never had to touch the

JIM; is it you can go higher on voltage or capacitance?; or both, I forgot?/; thanks, Steve There's a little bit of clock removal and testing information on my (revived) website: http://userweb.windwireless.net/~jimc/mamerepairs.html and, buried in here, how I fixed a 107 SL clock:

JIM; is it you can go higher on voltage or capacitance?; or both, I forgot?/; thanks, Steve Both, really. It's a pretty non-critical application. What you usually find is that the capacitance has dropped substantially in a failed clock. Though I've seen shorted capacitors too. -- Jim
