The suitability of 10 GHz gyroklystron amplifiers for driving e-e+ super-colliders is being studied. First, an experiment will be carried out to demonstrate peak power of 30 MW together with high gain, good efficiency, and low phase jitter. Second, extrapolation to 300 MW is anticipated. The present paper presents designs for both 30 MW and 300 MW based on 500 keV electron beams and symmetric TEOn modes in circular gyroklystron cavities. Stable amplifier operation is expected, since the current is well below the threshold for exciting oscillation In the cavities, and the drift spaces are designed to heavily load the modes which are not cutoff.
