I've had various Henry amps with edge-wound roller inductors as the primary PLATE tuning mechanism. My last one, a Henry 3K Premier, used that. It used plunger-switch selected (activated by cams on a

Depends on whether the amplifier has a band switch which selects fixed "Tune" capacitors for each band or a continuously variable "Tune" cap. In the former case, one uses the inductor the same way o
