Wonderful Noise Source

I just finished a quick experiment and considering my lack of electronics
knowledge am amazed that it works as well as it does!

I took Gene's Noise Source design from the ASM-1 and built it up on a
breadboard.  I then added 'Q' controlled random noise output from ENS-76.
This all works great as expected.

I then added a simple three band equalizer circuit off the white noise
output. Circuit is from the Application Note #1 supplied with the 2N2712
Noise Transistor from Midwest Analog Products.

Wow!  Talk about control over the pitch and depth of the noise output!
Forget about White, pink, red, whatever color noise.  This gives independent
control over the low, mid & high frequencies present.

What I have running is probably the most panel controls ever seen on a noise
source!  It has a level control (Gene's trimmer is now a pot), Q control on
the random noise output, and low, mid & high pots on the equalizer.
