A solid-state kilowatt amp kit on the horizon?

pa1000

I’ve never understood why no manufacturer offers a 1000-watt amplifier kit (though Ameritron comes close with their amps needing a thorough look-over before power is applied). I think there is a market for such a kit and have thought that if one was offered, it would be based on a 3-500Z or some other tube. The…

QRP as a religion
