Title: Variable resistor symbol in schematic?
Post by: Papa Jim on February 03, 2019, 08:48:46 pm

In the tone stack of a schematic It shows the treble and middle pots like normal using all 3 terminals. The bass pot is just shown with terminals 1 and 3 connected and has an arrow drawn across it's resistor symbol at an angle but not connected to anything like it is a variable resistor. Am I to assume that the wiper is connected to either terminal 1 or 3 to make it function.?
