Subject:      suppressing electrical noise
Content-Type: text/plain; charset="iso-8859-1"

further to the recent thread on grounds, etc.,  I've had tons o' problems
with eletrical noise coming through my radio, tape deck, & amp.  It's coming
thru direct connections to the battery, take-offs from the cigarette
lighter, & wiring from the fuse box (ie, everywhere).  I'm pretty sure that
most of the noise is coming in thru the power supply and not through the
ether because I have a portable cd I plug into the stereo... if i power from
car, there's background noise, but if i power from AA batteries, it's clean.


Anyway, are there any basic steps to take to suppress electrical noise in a
Vanagon?

- OR -

Can a cheap, effective electrical filter be purchased for the radio/tape/cd
player that actually works? (thereby bypassing all the work & mysticism
maybe associated with actually trying to fix the problem)

(corollary:  Can a cheap filter be purchased for the power amp?  I guess 100
watts or so, where the head unit with its smaller amp is maybe less than 10
watts)

- OR -

Is it easy to fabricate effective filters?  (it's occurred to me to try
using power filter circuitry from an old PC power supply, but no idea if
this would work)


Whew, that's a bunch of questions...
