1,500W / 4 Ohms Power Amplifier Rod Elliott (ESP) Introduction
... output devices. Although the MJ15024/5 are rated at 250V, they will take more because the base is tied to the emitter with a very low resistance. 1200W into 8 ohms is quite possible, with around 2kW into 4 ohms (or 4kW / 8 ohms in BTL configuration). I suggest that the number of output devices be in ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
