So Sick of SEARCHING, help me find a good +/- 24v regulator PLEASE!

Yes, this is possible.
To make 2 LM317 circuits. Identical.

And then you stack them one on top of each other.
One for the positive half
and one for the negative half.

One hook only:
You have to use Transformer with 2 Separate windings!
( one with a common middlepoint for Ground, will not work )

So make sure you buy 2 x 12 Volt trafo. Or what voltage you will use.

Hot deal 🙂 I got two of them.

An externally hosted image should be here but it was not working when we last tested it.

The idea is like this. This is for higher current (LM338).
For preamplifiers and currents max like 1 Ampere we use LM317.

I'm glad to see you guys hav e gone down the LM3xx route. These are great regulators and bes t of all their performace is good, consistent and they work every time.

16 56uf FM Panasonic capacitors (output capacitors, four per output, should be super low impedence)
$.14 x 16 = $2.30

You don't want super low impedence caps at the output, at the contrary.

Read the serie "using 3 pins regulators" on this website: http://www.acoustica.org.uk/ You can also find more reference on this forum doing a quick search.

I might go slightly simpler since 1a per circuit is just overhead room.

I can go with different capacitors. You sure I want not low impedance feeing the JFETs? I could go with some BGs or FCs instead of FMs.

 

[astouffer]

Low impedance caps are better suited for switching supplies where ripple is in Khz or even Mhz, not Hz.

 

[ostripper]

Yeah , just standard caps will do (high temp. maybe??)
derate them good (35v-50v), use multiple caps
on each rail (better than 1 big one) you are good to go.

I am going to put a .1ohm resistor between the capacitors and the output lead on the LM137T's and it will fix it.
