[ARC5] Adventures in Battery Ops - filters.

[Kenneth G. Gordon]

Bill (and group):

Some time ago, your middle son, who at that time knew everything (I'm not 
young enough to know everything) decided to build himself a hot-rod 'pooter 
using parts which were as inexpensive as possible.

One of those items was a "really powerful" 600 watt power supply.

As soon as he fired his new creation up, every single radio and TV in the 
house exhibited horrendous noise.

I was not aware what he had done, so I got out a small AM radio with a 
loopstick antenna in it and went "looking".

It didn't take long to zero in on his new 'pooter.

I removed the power supply while he was gone, opened it up and took a 
look. It was the cheapest looking thing I have ever seen, the case metal 
being about as thick as that in an aluminum beer can, and, of course, there 
were ZERO filters in it, although, like you, I found silk-screened places on 
what passed for a circuit board where those parts should have been.

After buying and replacing that POS with a real power supply, I took the 
errant supply to a friend's target range.

Several magzines full of 7.62 X 54R applied to the POS from 50 feet or so 
was a very satisfying experience for me.
