Thanks for the reply Bill. I remeasured the current. KRX3 on 1.82A off 1.52A so if the extra current is consistent with the KRX3 on and off with your measurement then I've got an extra 400mA sneaking off somewhere? 73, Peter VK3IJ -- View this message in context: http://elecraft.365791.n2.na

I know this is like asking how long is a piece of string but like they say, if you don't ask I recently replaced the volume control in my rig and since then if the rig has been running for an hour or so I notice the smell of an over-heated component when I come into the room. The front of the rig
