I am posting this message for a friend (Bob Lindstrom).  He will see all
replies here, or you can respond via e-mail to boblind@percival.UUCP.
-------------------------------------
	I seem to have discovered that my lowpass filter in the A2000 has
channels wired in reverse of each other (if that's even possible). When I 
run Mark Riley's LED program to disable the filter, the left channel clearly
loses its high frequency response and the right channel acquires additional
highs (as expected).
	When I run the program again to enable the filter, the left channel
sounds nice and crisp and the right channel is the one that grows slightly
murky in sound (again, as expected).
	Man, this thing is wierd. The left channel apparently behaves just
the opposite of expected while the right channel appears to be on target. 
However, I dread having to explain this to one of our local repair outfits,
much less trying to prove to them that it is actually happening. ARrgggghhhh..

		Thanks,
		Bob L.
