>Found this on AES, will that work?
No not for this. It's a 7815. 78=linear regulator 05= 5v (fixed, nonadjustable).
The LM-317T is an ADJUSTABLE regulator. It has 3 terminals, in, out, and voltage set. You can put up to 37vdc in and adj it down to as low as 1.2vdc. Max current is 1.5a for the T version the K (TO-3 package) will do 3a.
The pot allows you to continuously set your output voltage ANYWHERE from the input voltage (in are case 10v) to 1.2v
You might want to grab a few extras as they are real handy when building lv p/s. I'm not sure how it does it but the output ends up being cleaner (no hum) than the input which may have a little.
On the B supply you could buy a 6-10k power resistor w/an adjustable slider to set the output voltage. Like this one.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
