Default Re: Trouble with a 706 faint dial tone.

Did you try a different dial? Only 5 screws though you need a nice small screwdriver and musn't apply too much pressure.

If still no luck, a cracked track is the likely suspect. Do plenty of "cold" checks with a resistance meter, including from components on the main PCB to components on the regulator, to check for poor contacts between the two too. And have a good look with a really strong light. Brush the PCB clean with a stiff brush first.
