> 20 Minimum Hfe on a BJT Power Transistor?
The Motorola MRF454 is an RF power transistor.  The datasheet says it is intended for operation up to 30 MHz, calls out minimum hFE of 40, and says the device is rated for 80 watts power out.

This is probably not what you want if you are looking for a high-gain 2N3055, as the 2N3055 is intended for DC operation.  It is a linear power supply pass transistor.
