Also it is possible to connect Ug1 and Ug2 directly to the grids, and measure at other side of the board, via the banana jacks, what the grids are doing. This is probably the most common way to attach the grid. For the input, use the pads (In-1 and In-2 at the other side), and from there wire it with a capacitor, or whatever the circuit is.
