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.

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.

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.

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.
