What is this wiring diagram symbol? Answered

It's part of the power supply circuit and probably has something to do with the wall wart power supply, but I'm not confident enough in that explanation to move ahead with it.

It's a power socket, "barrel". The outer is -ve / GND and +9V is the centre.
For one of these / or one end of.

If you look at bunch of electrical stuff in a store, you'll see that some things are configured the opposite way.. with the negative on the outside and the positive on the inside. It matters.
So if you're trying to substitute or replace something, those symbols have to match.

I said "The outer is -ve / GND and +9V is the centre"
You said "the opposite way.. with the negative on the outside and the positive on the inside" - that is the same, not opposite.

Oh. Sorry, Lemonie. I thought the image meant that the inside was negative and the outside was positive.  Wrong, huh?

Easily done.
(there's a little + on the inner connection)

OK, I see the +... but what's the gray line with the little - going to the inner circle?
(I've only seen these things embossed on plastic... black on black.) Bet I'm missing something REALLY basic here.

The gray line is an electrical connection, you use the symbol in circuit diagrams.
