Dear Andy, LF group, To a reasonable approximation, the voltages in the tank circuit, and the guard circuit, will vary in direct proportion to the supply volts for a given value of load impedance. Th
Aha... wondered why you hadn't mentioned it before - unfortunately, the guard circuit is not shown in the simplified diagram in the LF handbook. What it is - the tank coil has a link winding on it. T
