I forgot when I rewired my Time-O-Lite timer. I started with a 23C-II
enlarger and it had a condenser head and a 2-wire plug. I then got an
Aristo head. And later a Zone VI VC head. At some point, one of those
had a 3-wire plug. I took the timer apart and put a three-wire socket on
it, and a 3-wire power cord as well. Problem was that a regular 3-wire
socket would not fit, so I used a Hubbell twist-lock socket instead. So
I need a mating plug on whatever it was. I do ground the enlarger to
reduce static. I do not know for sure if it makes any difference.
