TIP50 + LM317 High Voltage Regulator

bee696 · 2nd August 2005, 08:53 AM

Dear all,

I'm looking for the the captioned schematic. Actually, I stored in my PC but I can't find it

Pls help.

hi,

if you know what format it is, example, .jpg. then you can use the "search" function in your pc. if its there you will find it.

No TIP30, but is this along the lines of what you're looking for?

These are variations on the tried-and-true Maida design, which I've used successfully many times in the past - all the way up to 1000V! The problem has always been that high-voltage bipolar transistors have low current gain, so you are forced in many cases to use a Darlington configuration. A buddy of mine just built a Maida variation using a 1000V MOSFET (in a TO-220 package) to stretch the voltage, instead of a Darlington pair. Works great he says. I don't have the part number but I can ask if anyone wants to know. There are surely a large number of high voltage MOSFET types available.

Hello. For a MOS-FET version, check the following site of my friend.
http://www.geocities.jp/shoranosekai...irozu2of2.html

The original design was introduced by Mr. Kato (JA9TTT). His site no more carries the drawings. I have followed his design and enjoy verious kinds of high voltage power supplies for my tube amplifiers.

Check out the captioned SFM80 Schematic here:
http://www.diyparadiso.com/proj/sfm75.htm
Don't worry about his SRPP comment at the top of the schematic, not a SRPP in sight.
The whole front end circuit is available as a kit or PCB only from Curcio Audio Engineering (CAE). IIRC the PCB-1A. Of course, no circuit value on the schematic at CAEs website.
I've built a few of these - works well.
Cheers,
Ian

Dear all,

Actually, I stored in my home 3 boards for sale.
If somebody need a board i can sale them.
my mail walter_burkhardt@web.de
