Default Reverb trouble-Schematic reading help needed

GA-620.jpg

I need help attaching the wires(+,-) from the reverb pot to the SPK003 circuit board. They were un-attached when I got the amp. Any help is greatly appreciated.

Hi, As far as I can tell from the schematic ,reverb pot 500K ohm has
3 terminals, one to pin 35 of spk003 board and live terminal of jack.
Center leg to pin 12 of spk002 board.Third one to ground.

You have to check the pot that when you turn fully anticlockwise to get
maximum ohm or minimum ohm? and vice versa with a meter between one or the other pin with
the center pin because the 2 extreme pins will read maximum as rated on the
pot.eg.500K ohm either way. Try it one way or the other.
PS where does the + and - go to the pot?

Thank you singa! Finding my way around that architecture from the schematic was too foreign for me.
