So the power supply on my Capcom Bowling decides to die. No problem! I'll just order a replacement from Bob Roberts...
I get my new power supply and it has this knob on it, obviously for some sort of voltage adjustment.
My old power supply didn't have one.
So the two questions are:
Does it make a difference if my old one has a knob or not?
and
What is the knob for?
