Who would believe it?
I followed the circuit shown in the URL below and purchased a few old camera slave flash units.
Extracted the required parts from the flash unit and wired it up.
The power supply comes straight off the HT coil which belongs to a machine made up from Oztules circuits a few years ago. I am not sure if the HT transformer is out outing full power and suspect a short somewhere inside. Never mind, I have a few new coil units that just require the secondary winding and I should be back in business.
So there we are, something that tells me that the electric fence is working. Wonderful, its made my day!
Any comments will be read with interest.
