Sorry, Barry. I did see your post but I didn't understand the 2 coils bit. I was wondering if the 2nd coil was useable as the one being used is clearly defective. Without the wires connected to the head I can see the correct signals on my scope showing the bias at about 48k and sound from the microphone superimposed. With the wires connected to the head - nothing. So I'm sure the head is faulty.
