Knob for HH Scott LK-72

dcmeigs

I need a single volume knob for an HH Scott LK-72. These are brown with a gold ring and are "dished". By that, I mean they are shaped like a dog bowl. They are about 1 inch in diameter at the back tapering to 0.9 inches in the front (truncated cone) and just over a half inch deep (0.525").

These amps had duplex knobs too for bass and trebble, but I'm looking for the ordinary single pot type.

Thanks
