The Yaesu FT-901DE is a tube-hybrid HF transceiver from 1978, covering the classic nine amateur bands from 160 to 10 meters. With up to 100 watts PEP on SSB/CW, it was one of the more capable home stations of its generation, though FM required an optional add-on module. It is characterized by its combination of a solid-state receiver and a tube final stage (12BY7A driver, two 6146B finals).
