You don't have to re-invent the wheel for the amplifier power supply in this case.

Well, this is in the spirit of Mr. Marsh, see atachments, reposted from here:

Corrected version.

Rail splitter lifted from here:

Are there any pcb for these available to us?

I believe this was the first publsihed application for audio use. It has been my favorite topology ever since.

Not at the moment, but I will put something together in a day or two.

R8 should be 2k5 for bjt input opamp, right?

How well does it deal with ripple at the higher frequencies?

On board C-multiplier will filter all the remaining HF noise.

Just parenthetically, I do wish that Elektor would publish TAA, Glass Audio, Speaker Builder as a set of DVD's. There was one set of the issues of the 1970's placed on CD which is nice to refer to from time to time.

Nice idea. I'll talk to them, though note: Elektor no longer owns AX.Steve Ciarcia bought back both Circuit Cellar and AX....

Steve coined the phrase "software in solder"

There were a lot of new and interesting ideas in those mags that ought not to be lost and forgotten. If nothing else... someone around here can start asking for issues in pdf to be submitted for a single point contact place.... if the owners dont mind and are not interested themselves in doing it or DVD of them.
Anything I did, i kept copyrights to it and freely give anyone permission to copy them in full.

I have no time nor talent to make my own pcb from your layouts. can we order them already made?


THx-RNMarsh

 

[sikahr]

Peace of cake, Mr. Marsh, I don't expect You to do your own layouts.

I post layouts asking for help from others in verifying design & checking for errors.
As soon as layout is verified, I will order my PCBs&enable ordering for others.

My past PCBs as examples:

10x8 Dual Power supply DC board with RCR(L)C filter

Keantoken Kuartlotron

5x5 Super regulator

Keantoken K Multiplier

Final check please...

> 5x5 Super Regulator

Have you asked Mr. Didden & Mr. Jung whether you may use their names / circuit ?

Nope, didt't care much about these things. First posted to diyaudio, seems nobody cares.
Please let me know if I break some rule.

Not very clear to me why you ask this instead of Mr. Didden & Mr. Jung.
What are you, some kind of diyaudio police?
