Default Look for high-voltage regulator projects

Hello,

I want something to regulate around 250V to 300V. Can you give me some information, curcuits, or website about high-voltage regulator (soliid state or tube) projects. Thanks

Hi Mrpong,
Have a look around this forum for preamp threads. Some of these may include a supply that is what you are looking for. There is also a power supply forum here under "Other Stuff" .

I imagine between those two you should be able to come up with something that fits your need.

Chris, I can't believe you didn't point at this!

Hi Giaime,
You have a bad link there!

I can't remember everything! That's why you can post too!

I am sure that will help if you can get the link working.

Hi Mrpong, Giaime is kindly directing you to an on-line copy of the Radiotron Designers Handbook. An excellent reference. I have a copy of the actual book and can recommend it. Another top notch book would be "Valve Amplifiers" by Morgan Jones. More up to date. If you are interested in tube electronics at all, get both of these at the very least, I'm very glad these are in my library.

-Chris

(Now it works Giaime! )

Chris, the link was on my Mosfet regulator, not for the RDH4. However, here's the schematic I was linking:

Hi Giaime,
I know. Sorry, I wasn't clear enough.

You have a link to RDH4 in everything you post. Did you click on your link? I fixed it and it does link to the same as your attachment. I need to articulate my meaning more clearly. I think in shorthand.

I really like the look of that regulator, can anyone vouch for its preformance, because it looks like a good power supply for a phono pre-amp

Sorry for misunderstanding Chris however my link worked out for me from the first time I posted it.

Alex, yes that's what I use to regulate B+ in my preamp. See details here: http://www.giaime.altervista.org/mypreamp.html

The original schematic is the Maida regulator, in a National application note: see here http://www.national.com/an/LB/LB-47.pdf

Hi everyone,

Sorry to jump in like this. Here is a link to a tube-based regulated power supply: http://www.the-planet.org/6GV8.html

The page has a link in it to a pdf of the schematic.

I have used it in a line stage that I built - http://www.the-planet.org/linestage.html

Scroll to the bottom to "Baby Blue - A Western Electric Based Linestage".

Hope this helps.

Ashok

I Really like the look of that Phono Stage simple, only 1 tube (per channel), and I don't think I have ever heard/read one bad thing about the ECC88 so I have been looking to use them in a project. do you sell PCBS for the regulator, the pre-amp or both? or do you have an express PCB (or similar) file that I can use to make a board?
