The new version of the 6m/4m Discovery uses a Russian GS35 ceramic triode valve. This rugged triode valve will operate for long periods at an output up to 1500W. The output stage is a Pi/L network with a tuned input circuit.
A heavy duty toroidal transformer and voltage doubler board produce 3600V. The valve is cooled with forced air from a powerful centrifugal fan. The new Discovery features a specially designed control board.
Incorporating soft start and a 3 min start-up timer. There is also protection for Plate over-current, Grid over-current, Over-drive and internal valve flash-over.
