While that works, I prefer to have a heavier load on it, which you could do with a resistor. I also have a tester for the tormat selection receiver. I plug it into the receiver socket and an RCA plug into the pulse amp. When the unit is on the bench, pressing the switch on the tester pulses a 120 volt relay. That one started with a 100 watt light bulb, then changed that to the relay. Both relays are DC rated so they vibrate quite a bit with the AC pulses. If the receiver is still hooked up the the jukebox, I can still plug just the RCA plug in to see if it trips the the mech.
