I'll check the finals. I have some spares, just in case.
I'd love to be able to control the power out on the uBitX without opening it up and turning a trimmer pot. If it had a control for output power, I'd use it. The stock machine, as I'm sure you've noticed, doesn't have a way to reduce the output power.
So it is what it is. Perhaps I was naive that it wouldn't blow up while trying to tune for a few seconds.
