Whats this 630V stuff? 630V shows up in the digital article and twice in the magazine hard copy. Dies +/- = 6 in the font used? No proof readers anymore?

Take a MAX232 and a cat fur,and (gently!) rub them togheter.Now do connect a mVm to the cat's banana input and output. You will get 630V.If not,keep rubbing.Of course,you must be carefully to avoid rubbing out the cat. (attn.ASPCA:no animal will be harmed or irreversible depleted of her electrons in this experiment)
Otherwise,the article/circuit is useful.

Nice one...The old snake oil add.

The title says "Generate 630V" but the circuit generates + and - 30 volts! Am I missing something, or did someone make a typo, and nobody proof read?

Erratum?: Should the captions for p.60 design idea in the 07.20.06 issue actually read "Generate 630V...?" I believe the voltage figure idicated may be in error and should indicate rather "+/-30V" instead.
Thank you for your attention and good service.

Doh! You mean +/- 30V by any chance ???
(if it is really 630V we want a million of them !)

What a gyp, I was psyced for the 630v and all I got was a +-15 charge pump. Since there is so much dissappointment maybe someone will actually submit a 630v design.

Way to dig the editor, guys. However, the only reason I looked at it was the 630V spec. I'm sure the editor had a "perfect" year going until this typo!!!!!

I really wanted the 630V version!

C'mon now, let's have teh +- 630 Volts for a nice radio design.

Whoa, I was really let down. I really needed a 630 V supply but when I got to the article it is a plus minus 30 V supply. Still not bad but not what I needed.

The editor did you wrong. What should have been a "plus or minus" symbol somehow became a "6" which was then copied to the email headline. It's not a 630V supply, but it is a nice +/-30V supply :-).
