Is there a way to improve the grounding of the kit? I just built the kit and followed the 6L6 build guide. If there is a way to improve the grounding, what should I do? I'm thinking make a bare spot on the chassis and run a ground wire(s) to it but where should the ground wires come from -- pot, input, output, etc.?
So add a wire from the ground wire tab on the DC input jack, sand a bare spot on the chassis, drill a hole there, run wire from DC input jack to the bare spot, add screw over bare spot using hole drilled? Sound right?
