I can remember seeing/hearing someting a while ago about modifications that can be done to a computer PS to convert it into a HV PS. I can't remember where I heard this, but I have been given a couple of old 300W computer PS's for free and would like to modify one, so I was wondering if anybody happens to know anything about how this can be done?
Thanks in advance for any help anyone offers.

HV AT/ATX PS Mod
Hi Benny,
I seem to remember an article or two for modding. A guy had modded his old 250W AT supply to put out something line 350VDC@600mA for a tube amp. I will have to look it up and if I find it, I will post the link here.

Pic PS Mod
bEnnY-
I think I have it. I have tried to compress this pic with the evaluation version of Winzip, but it only lets me compress it something like 1%.
I'm sorry I don't remember where i got this pic, but I got it last August. Anyway, here goes......
Ok, I tried to attach it, and it's still too big. E-mail me privately, and I will send it to you.

Hey that's a neat photo and all, but how about a little more information... like where it came from, and how the modification was performed, etc...

Like I said, I don't remember where I found it, it was almost 8 months ago, but if I run across it again, I will post the link.

Modifying a low voltage SMPS for high voltage is a scary proposition if you ask me -- this would be fraught with safety & reliability issues.

Safety, Safety, Safety
That is why any project like this is approached with the utmost of safety in mind. While I don't necessarily endorse anything like this (I'm just passing on some info I stumbled across in response to another's query), I would be interested in how it turns out.
Another reasion why I like solid state- I am very alergic to high voltage.

That's from the July 2004 issue of Silicon Chip, an Aussie electronics magazine. They have a whole article on how to do it, though it is quite complex.
http://siliconchip.com.au/ They should be able to send you a back issue I think.
