Filling the gaps in my technical knowledge that is.....
Today I traced a signal (a square wave) through my GSSL clone to find a short and I came across something I did not understand.
Below you'll see a part of the gssl schematic. Between point A and B are normally the VCA's but I left them out (jumpered them) because I just wanted to test the In and Output part.
What I did not understand was when I probe between the 22u cap and the 27K resistor I see a square wave, but when I probe after the 27K resistor the square wave is gone. Then it reappears at pin 1 of the 5532, disappears after the 10K resistor (before pin 6) and reappears at pin 7 of the 5532.
What happened to the square wave?
