First you have to know which fixed resistor and it's value that currently controls the bias setting and then you remove that resistor and install a cermet pot in place of the fixed resistor value....If the resistor is 10k,you put an adjustable 10k pot in it's place...You do have to know what you're doing and you'd be best to pay a competent tech to do it for you...It's an inexpensive mod though..
