    Connect the Cathode of an Opto to the collector of TR1 and use a relay coil in the Opto transistor's collector. Then connect the AC line in series with the relay contacts.

    The original ultrasonic circuit already had a darlington pair of transistors driving a relay.

    This is what I was describing to you. The components shown on the Strobe board are existing components. Please don't kill your self! :rolleyes:
