Default Re: Quiet or no dial tone in a GPO 706

Hello Tony. I'm definitely OK with T9 and T19. There is a brown wire going from T9 to the capacitor and a green wire from T19 to the capacitor, as per the photo below. Admittedly the position of this green wire makes it look like an addition or alteration but I can't say for certain.

There is a brown wire from Pin 4 of the ASTIC to the gravity switch, second from the right in the photo below. It connects to a green wire ( far right of the switch) which goes to T7, not T19. I wonder if this green wire and the green from the capacitor have been accidentally transposed ?
