I'm curious, what makes RF amplifiers fairly expensive projects? I
admit I have no experience or exposure to them, but as far as I can
tell the two major building blocks are a power supply and a not
terribly complex amplifier circuit.

Is the bulk of the cost in the amp device(s) - power transistors or
vacuum tubes/values?

Thanks.
