Post by: soupbone on August 04, 2011, 06:18:12 AM
How do you figure out in a circuit which diodes are the clipping diodes?

They are in the signal path. They clip signal.  ???

there's usually two of them next to each other, facing in opposite directions

....Or, there can be 3 of them, or 4 of them, or if you're looking at a Tonebender or Harmonic Percolater, sometimes just 1.  They can be located: a) in the feedback path of an op-amp, b) going to ground after a gain stage, or c) in series with the signal (if crossover distortion is the goal).

Usually two, but not necessarily. There could be only one or there could be more than two. But usually two in opposite directions. But they do have to be in the signal path in some way.
