In 1985-1986, I actually used a transmitter with a solid state exciter board and a tube driver and final amp for FM pirate radio broadcasting.

Why? Because the 6146B VHF capable power tube was still available common and cheap at hamfests and two were in the house from a partially disassembed ham trasmitter my father had built a half-century earlier. I didn't have a source for decent VHF power transistors until late 2006.
