A different style classic Singer foot controller
I've only run into the one type controller before. Usually when I open them up they look like the brown one. This is the brown controller that had an overheat issue and even though I cleaned it, re-wired it and it works it makes me nervous. I dug into my box of spare controllers and pulled out this black one. The guts inside are similar but not the exact. Is this an older model? or maybe a younger one?
