John, there has to be a more interesting conversation. See my new thread, Programmable tracking pulse supply.
Thanks,

Where's that thread?
Cheers

Good catch- 390K into an input with a bias current of -4.5uA max
-1.1uA typical and a reference of 2.00V results in a huge variation.
Not only unit-to-unit but it probably varies enormously with temperature as the beta of the front-end transistors changes.
Just the kind of schematic one tends to find on the Internets.

Well, it's might be good enough for a bug zapper.
I had to create it first! Just posted.

Well, it is sometimes fun to play the game "what's wrong with this circuit?"
There are more things.
OK, but I probably won't be able to play my game. Party pooper.

^^ Oops.
Mosquitoes!
There are people here who can't tell "its" from "it's".
There is a newsgroup dedicated to the subject.

I just checked my newgroup directory on Astraweb and it wasn't there, so I subscribed to alt.gullible instead.
I believe that.

First off, idiot, IF you had looked at it, you would note that the reference is NOT 2 volts.
You are a goddamned retard.
What's the max output current?

Valid point, but it's still **horrible**. >26% variation from that alone.

It doesn't matter what the ref voltage is. The HV drifts by
(delta Ib) * 1e8
which looks to be hundreds of volts.

Look at the secondary winding wire size, and the multiplier caps, and do some math, pussy.
OK, you don't know. You don't know anything about this schematic, not a single fact. Where did you poach it from?
