I know my 2 Macs are, 1 you switch manually and the other does it itself, although I'll plug it in w/bated breath. Enlargers, timers, etc not so much and will need converters when I finally, if ever, get set up again. With my very limited knowledge of electricity I'm trying to figure out if I want one that will handle 3000 watts thus MAYBE allowing me to plug in multiple items,http://tinyurl.com/83l9pm8 , or maybe allow a surge protector w/multiple outlets to be plugged into it. Or if I should just get smaller cheaper ones. Thanks for the info re: Hz. Will be looking into that as well I guess =\. volts, watts, amps and now Hz. ________________________________ From: Laurence Cuffe <cuffe@xxxxxx> To: "pure-silver@xxxxxxxxxxxxx" <pure-silver@xxxxxxxxxxxxx> Sent: Thursday, November 17, 2011 8:29 AM Subject: [pure-silver] Re: 2 'Dead" Kearsarge Timers Sent from an iPad, On 16 Nov 2011, at 18:23, Eric Nelson <emanmb@xxxxxxxxx> wrote: Not sure exactly.

This will be marked on them if true. This applies to things like computers, camera battery chargers etc. It did not apply to my Epsom scanner, so always check and don't assume. For things with mothers in them, food mixers coffee grinders and the like, you can get a transformer. This will work ok, but in the longer term the lower frequency, 50 vs 60 he tends to burn out motors faster, even though the voltage has been changed. Bring extension cords so you can plug a couple of things into the one transformer, and trip over them at night. My 2c. Laurence Cuffe
