Removed the ground wire and there is no short to earth (with the feedback connection to the preamp it measures just over 100kohm which is correct and with it removed it is open cct).
Had a look at the Geofex site but couldn't find a transformer tester (will carry on looking).
Checking the resistance of the secondary (after allowing for the resistance of the test leads) I get, White-Green:0.1ohm, Green-Black: 0.1ohm, White-Black: 0.2ohm which adds up ok but I've no way of telling if this is too low or not.
How do these figures appear to you?
