[Jukebox-list] Seeburg Q... where's the service/scan switch???

[jhayes2613 at aol.com]

 Yes, I see on this replacement plug that there is no difference in either post (color or otherwise), so I assume that I'm good to go. Please forgive the dumb questions but better safe than sorry--!
Many thanks-
j

The terms positive and negative apply to DC current.  You're dealing with AC
here, where which conducor is positive and which is negative changes
120 times a second (at least in the us, with 60Hz power).  

So the terms used are hot and neutral.  Since they switch positions
all the time, there is not a lot of difference between them; most
things will function just fine with the wires reversed.  You'll often
find outlets with reversed wiring, especially in older houses with two
prong outlets.

But the hot is the leg that goes through the fuse or circuit breaker
at the pannel, the neutral is kept at ground potential.  So there are
safety issues, like you want the threaded outer ring on a light bulb
to be neutral, because it's easier for a person to touch by accident.

Hot = gold = black, neutral = silver = white.

Googling for ac current, this was the most promising explanation that
popped up in the first few results:

Within jukeboxes and other electronic equipment, AC is converted into
DC for some circuits.  Amplifiers are all DC internally as far as I
know, yet turntable motors are nearly always AC -- their speed is
controlled by the AC frequency, thus so is the speed of the record.
The credit and selection systems are usually DC.

Hope this helps you.
