In Reply to: FWIW if you just have a grounded wiper it works exactly the same. posted by Ralph on April 17, 2025 at 08:15:36:
Without the grounded center tap the shunt resistor in one channel goes up in value as the shunt resistor value in the other channel goes down in value.With a grounded center tap the shunt resistor value in one channel stays the same as the shunt resistor value in the other channel goes down in value.
How can you say that "it works exactly the same"?
They would both be balance controls and they would both work (and maybe that is all you meant) but they are not working the same way.
Sorry for the poor drawing.
