can you add one to a 3020 I understand they have no tape monitor

Does the 3020 have preamp out amp in connections? You could hook up the EQ there

why yes it does:scratch2: is the 3020 much different then the 3020A face plates a wee bit but anything else?

If I remember correctly, the only real difference is the placement of the power supply filter caps, and that the voltage regulator is on the main board instead of attached to the back wall.
