keith - I've looked at the jack on the front and there is nothing obvious shorting any og the pins. Checked pins against each other and against chassis grd with vom and no continuity between any 2 pins. Only continuity is @ pin 2 and 4 to chassis which should be normal as Pin 2 is a direct grd (E)and Pin 4 is Mic. grd (ME). Any other thoughts ?
