so i purchased few amps from local audio installer and one of them is a older fosgate t20001bd .amplifier powers on and idles fine ,has a good output but there is audiable high pitch noise in the output with or without rca connected to the source .the only visible part that is damaged is the resistor shown-its located by the speaker terminals

How loud is the noise when you connect a subwoofer to the amp?
Do any of the switches/pots affect the noise?
What is the amplitude of the noise on the speaker terminals when viewed on a scope?
