Hi again.
Can this high voltage circuit be improved/simplified.
This schematic is included with this Scope Clock kit
I would like to have a final voltage of 3000v
I am trying to drive a larger CRT that requires more voltage.

AZ- Nucleonics used this multiplier with a 1:3 audio transformer to give 300V AC @ 60 Hz for input for I think about 1.2kV for a neg. ion gen.Measured 10 uA ion current.Caps .1uF @ 400 V, Diodes 1N4007 . What current do you need? The Electronic Goldmine, Cat. # G1783 120 AC = 7.5 kV out, G 16821 high V transformer; G 16565 12V DC = 1000V @ 30 kHz, add doubler or tripler.

It's not going to work with a DC voltage source. Here is a link to voltage multipliers - http://www.play-hookey.com/ac_theory/ps_v_multipliers.html

Be careful - the current is limited, but the voltage is dangerous. This circuit must be built with care as to layout and mounting inside an insulated enclosure.
THANK YOU!!! I've been wanting to know how those circuits work, I've studied them, asked professors, and I couldn't get anything. THANK YOU.

P.S. If it isn't already on the "book"? section of the site, why doesn't someone put it in there? Liabilities?
