Drops right in, drain for plate, gate for grid, source for cathode. An IRF 820 has both enough voltage rating and more than enough current and power ratings to do the job. And the IRF820 is about $2.00 each, doesn't need heater current, and won't wear out like a tube will. Type: n-channel Drain-to-Source Breakdown Voltage: 500 V Gate-to-Source Voltage, max: ±20 V; Drain-Source On-State Resistance, max: 3 mΩ Continuous Drain Current: 2.5 A Total Gate Charge: 24 nC Power Dissipation: 50 W Package: TO-220AB.
