I need 1 simple little picture of where the volume knob solders to the rx 14 board with the volume knob in the picture!!!!! CANT FIND A PICTURE ON THE WEB ANYWHERE!!!!!!!

It's not of mine [too late to break it open, but found these on the 'net] The picture of the RX13 board is of my first tank, first time I opened it up and it matches in location to the internet pictures of the RX14 - same solder points
