I recently ran a two-tone test and measured CW power gain. (SN1078)  It doesn't look good.  The two-tone waveform shows distinct "flat-topping", and the power gain drops 25 percent from 1000 to 1500 Watts.  My old 3-500Z amplifier is much better.  Has anyone measured IMD or linearity, or seen any test results?

While I'm primarily a CW operator, I'd be very reluctant to use the amplifier on SSB.
