I modeled this CCS in LTSpice and voltage and current are right on the money when I fired this thing up. Seems to perform well and doing its job.
However, I stumbled on an issue when I fired up the amp with a 1volt signal at the input. The 150v at the plate dropped to 108v upon starting up the amp, when I removed the signal, the plate voltage stayed the same, it would never settle back to 150v. If I start the amp up cold with no signal again, everything is fine. I remember reading something about using a diode across the the CCS but don't remember where to put this.
