First Class-E Flyback Plasma Speaker

My first Class-E plasma speaker. Flyback transformer is resonant at 120 kHz, and is driven by a push-pull Class-E amplifier. The bus of this Class-E output stage is modulated by a Class-D amplifier with a PWM frequency of 200 kHz. Unfortunately, before I got a chance to package it up nicely, I managed to burn up the diodes in the flyback.

When it was working, it drew about 5 A at 30 V from the bench supply. Gotta love having a 300 W bench supply...
