[Amps] I'm not kidding: TL922

[Carl]

One of the things I did to sort of get even with people that got me angry 
was take a little HB
audio oscillator tuned to a bit over 20 kc and a submini speaker and turn it 
on and watch the reactions.

Most of my targets were banks that wouldn't give me a car loan, an over 
reactive judge that
fined me $50 for a short burnout at a light, and similar. Hey, I was only in 
my 20's and $50 was a lot of money in 64!

People rubbing their ears or faces to no reacting and bank guards and cops 
getting real antsy
sinc they knew something was happening but didn't know what since they 
couldn't hear that high.
If I lowered the frequency women would get real antsy and noisy which drove 
the guards and cops nuts.

A friend built one and had fun in church and bars!
