Abstract: A triode based 20 kW cw (continuous wave) amplifier has been developed and tested indigenously at 91.2 MHz and 70 MHz. The equipment will drive the pre-driver stage of 200 kW, which will, in turn drive the final stage of 1.5 MW of rf power to heat plasma in SST-1 Tokamak for 1000 s. Various aspects of design and fabrication of the amplifier are discussed in this paper.
