Filters seem to screw audio up when used improperly.
AFAIK, in a standard NPN common emitter amplifier, a filter can be obtained by connecting a capacitor between collector and ground (correct me if I am wrong).
So in my radio, I have three of them, one which is in my push-pull amplifier. When I change one value by a small amount, the whole radio goes wacko. I change it to another, it goes special.
The IF frequency for most commercially made FM radios is 10.7Khz isnt it?
if it is, I think I turned my d**n receiver into a jackpot!
LMAO :lol:
