Eric,
I reloaded the firmware tonight – no change (in fact I upgraded it from 1.47 to 1.54). If I plug the mains cable in the fans power up immediately. If I then turn the amplifier on, the amp works normally. When I power it off from software or the front panel the fans spin up and stay running. Is there something I can look at here in VK I wonder? I really don’t want to have to ship it back to Elecraft for this.

I then turned the amplifier off via the front panel push button. I would have expected the FANs to start up for about 10 seconds as they discharge the 60V rail supply but instead the FANs continue to run. the only way to turn them off is to unplug the amp from the mains supply. It is definitely a fault condition and not a menu selection.
