Hi one of my vestax pdx 2000 decks sounds a lot quiter than the other,everything is working correctly onit and i have been told it may be something called the output pcb, but i dont know what that is or if i need to repair it, its never been tampered with inside or undone so all the wires are ok and the tonearm is working, ive tried adjusting it but it is fine and i have also made sure it is earthed correctly, i can hear a slight humming noise theough in the background, is there any advice you could assistance me with please?

many thanks for any help, steve :) i really wanna get back up n running with my mixing :)
