The advantage of 240V operation is better voltage regulation, due to half as much IR drop in the wiring between the breaker panel and your power amp. The obvious disadvantage is that you need to change back to 120V to run the amp on a generator or from someone else's QTH. It's a fairly simple change -- you need to change the connector on the power cord (or use a power cord with a different connector) and change the fuse holder. I can't imagine running a power amp on Field Day -- it would be like tossing a you know what in the punch bowl. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
