Still not getting it. I have been tracing my input though the circuit and i
loose it entirely at the 2.2nF Capacitors. so i have no input into the base
of the 2n2222. I have no idea what is wrong unless i have the wrong
capacitors. Does it matter here what type of capacitor that you use. I am
useing Polyethylene Metalized Film capacitors. I can not imagine that this
would cause any problems. What kinda of caps are you guys using that got the
filter to work?
