Ricus:- I don't have a timer. Just a transformer for 220V in and 12V, 9A out. The nominal mains voltage in SA is 230V but it does vary considerably so 220-250 V is probably a better description. I have a UPS that I need to set up over the holidays, so I'll cable the enlarger to the uPS so at least it should get a steady voltage. Thanks a million for lookng for that lensboard for me!
