Dual pot in a mono gain circuit
Is there any particular reason why a dual unit pot is used in a single channel circuit (gain)?
The schematic shows 10ka and the pot is a 20ka Alps which is paralleled by the PCB traces. http://uk.farnell.com/jsp/search/pro...jsp?sku=642990 /Hugo |

Can't seem to find a schematic there, but a lot of times dual potentiometers are used to form a constant impedance attenuator.
