A frequency lead makes the Emarhavil Heavy SSTC behave better.

We add a frequency lead to the PLL, and turn the power up.  We're now running half-wave rectified, half power, from the variac.  It is quite a bit louder than it sounds in the video.

Additionally, we slotted the topload in the hopes that it would reduce the topload heating that we were seeing, hoping that the heating effect was coming from the topload behaving like a shorted turn.  (It didn't help.)
