Hi Trevor, It's not a particularly nice arrangement having the volume control progressively bypassing signals to ground when turning the volume down.
Anyway, the Premier Radio uses a vari-mu RF amplifier valve so there should be no necessity to employ such an arrangement, things might be different when a sharp cut-off valve like the SP61 is employed. I've disconnected the aerial input coil from the volume control and now it works in a much smoother manner as well as a slight improvement in sensitivity.
