It's not a switcher. As is common for linear power supplies (and not uncommon for switchers), there's an input voltage selector as part of the input power connector/fuse/switch combo.
Since the power transformer is 15 of the 22 pounds weight, one of my thoughts was to ship that part (or an extra) ahead when traveling, and when I asked was told that currently it takes about 15 minutes to install, but that time might be cut. 73, doug From: "Bob McGraw - K4TAX" <rmcg...@blomand.net> Date: Sun, 18 Apr 2010 16:24:43 -0500 Any switching supply today and one that's "worth it's salt" should operate satisfactorily from 100 VAC to 250 VAC. So 120 VAC or 230VAC should not be of conern. 73 Bob, K4TAX ----- Original Message ----- From: "Don Wilhelm" <w3...@embarqmail.com> To: "David Ferrington, M0XDF" <m0...@alphadene.co.uk> Cc: <elecraft@mailman.qth.net> Sent: Friday, April 16, 2010 3:40 PM Subject: Re: [Elecraft] KPA500 > David, > > Because not all have hamshacks that are wired for 220 volts.
