There's no such thing as an exact match in plugpacks. I've yet to encounter one that was within even 10% at rated load, and with no load it's more like +50%. > voltage notebook one, marked up to $130-something, which is around the price $130? Bloody hell. What a rip-off. There's bugger all in them - a typical plugpack contains a cheap transfomer, a bridge rectifier (four diodes in a single package) and, if you're lucky, one or two electrolytic capacitors to smooth the output. You should be able to make one for around $30 or so, even at retail prices. > of a new scanner. I'm not fully convinced I should run it out of spec. :-) I wouldn't expect it to matter. If the voltage is even slightly critical it'll have an internal regulator - if the original power supply really is a plugpack and not an external regulated supply - so as long as you're withing cooee of the right voltage you'll be fine. Current capacity is far more important - make sure the replacement plugpack can supply enough. Look at it this way: your scanner is stuffed anyway without a power supply, so what do you have to lose? :-) Cheers, John -- whois [EMAIL PROTECTED] GPG key id: 0xD59C360F http://kirriwa.net/john/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
