HELP! problems with audio detection circuit

dhenry:

  1. no idea what "led" you are talking about.

  2. the voltage I was talking about was the respective points vs. ground.

  1. i meant from the output (0-3v) to the ground.

  2. oh ok, sorry.

q1: b = 0.63v c = 0.86v
q2: b = 4.5-6.5v (depending on sound) e = 5v c = 0 - 3.5v (depending on sound) (the led lights up to sound from this pin to ground, but it doesnt have the slow decay which i am assuming is what the next transistor is for)

q3: e = 0v (no matter what sound), b = 0v (no matter what sound) c = 0v (no matter what sound)

so I am assuming the problem is somewhere around the last transistor...
