First of all, please excuse this super simple question. I know nearly nothing about electronics, and just want to make sure my understanding of this is correct.
So I ordered two of the same audio amplifier board (from different sellers), and the first one's potentiometer just sort of fell apart as soon as I inserted a screwdriver. I tried but couldn't but it back together.
I think, I don't need to mess with the amplifier's volume for this project, and I was planning on having it turned all the way anyway.
The exact model of the pot on both of them, I believe, is RM065-103 (datasheet here).
I have no idea how to read schematics, but I'm guessing that to replace it, (after desoldering and removing the pot,) the 1 and 3 pins (in/out?) should just be connected directly, and the 2 pin (gnd?) just be left alone, like this:
Is this the right approach to take? I tried researching a little bit and I think I might need to have a resistor between the connection, but I'm not sure.

I expect that the terminal you marked "2" is the wiper (moving contact), and "3" is the top (ungrounded, input) terminal. If you want maximum gain with the pot removed, jumper "2" to "3".
