RE: RH84 : LM317 CCS for EL84 ... zeners

I also tried adding the zener diode to drop voltage to g2 from B+.

Instead of the single 21V zener, I used (2) 6.2V Motorola zeners in series and a 22uF cap to ground.

The g2 voltage sits slightly below the plate.

When I get more measurements, they will be posted.
