[Elecraft] KPA500 Fuse blown
I was in the WAE rtty contest today when I heard a pop fizz, Red fault lamp on the kpa500 was lit up and 60v err in the window. I reset this fault, (switch off, and on) 2 hrs later I had another err fault, this time 270v err, I again reset the amp, 2hrs passed and had another 60v err, but this time the amp would not reset, it was powerless! Checked the Amp 6A fuses and they were dead. Is this a known problem! And can I get those 6A fuses here in the UK, or only available via Elecraft! Cheers Ken..

Re: [Elecraft] KPA500 Fuse blown
Hi Ken, The fuse used is extremely popular in the US so I'd be surprised if it is not also readily available in the UK. The common reference is type 3AG fast blow cylindrical fuse and it is 6 amp at 250 volt. Here's a Littlefuse part number 0312006.HXP. If you follow this link you'll be able to see a data sheet. The diameter is 6.35mm and the length is 31.75mm. http://www.mouser.com/ProductDetail/Littelfuse/0312006HXP/?qs=sGAEpiMZZMsIz3CjQ1xegWrlMY7vL59hjcmRNw8S59U%3d 73, Mike K2MK Ken Chandler wrote I was in the WAE rtty contest today when I heard a pop fizz, Red fault lamp on the kpa500 was lit up and 60v err in the window.

Re: [Elecraft] KPA500 Fuse blown
Ken, How much power out were you running on RTTY with your KPA500? I'm interested because I have the amp, but have not yet used it on digital modes (use the K3 barefoot at 25 W or so).
