+-85volt regulator

I just ran some tests on the "2 Transistor Regulator" shown above, 47uF on the output damps the response too much. 4.7uF is much better.

The original circuit is from Morgan Jones "Valve Amplifiers" 4th edition, page 381. While the article states that it is useful to 50mA, I found that once you go over ~35mA it starts to fade.
