ok, so i did some probing today,
i used a function generator app to get a constant stable frequency
and following the audio input path, i get the wave on both sides of the 1N Cap and 47K resistor and the input leg to the 10Uf cap, but nothing on the output of it.
i checked the polarity and its all good, and i also checked the cap with my meter and it seems all good aswell.
what would cause there to be noting on the output?
to my understanding of caps, as its directly on the input path, and there is no way for the audio to get around it, wont it fully suppress the audio waveform? in the first stage filtering part, i think that is a R/C filter? is that correct? In which case i can understand that the cap will filter some of the waveform, but the entire part of it can flow through the resistor.
cheers
