Here's a challenge for the collective genius of this group. I'm trying to replicate a lab setup, and all I have to go on is some grainy pictures. I've been able to identify most other components, but not this one.
Based on its location in the lab, I suspect it is a variable power supply, possibly AC, maybe even a bench variac. The resolution is just low enough that I can't make out the manufacturer.
Can any of you?
