Contrary to popular belief, when Mitsubishi discontinued common radio RF output transistors like the 2SC2166, 2SC1969 and 2SC2312, they did not leave any void in the replacement market. Radio manufacturers were in no way limited to the inferior power supply switching transistors they all use today, like the 13N10. Mitsubishi specifically designed newer, upgraded linear RF MOSFET's to replace them. The RD06HHF1 was the perfect MOSFET replacement for the driver stages and the RD16HHF1 would...
