Hi Charlie,
If you connect the switch common to the high impedance end of the tank you'll
add all the stray capacitance of the unused portion of the coil to the plate C.
Just what you are trying to avoid!
The traditional output end connection adds this stray C to the load cap where
it does no harm.
73 & Happy Post Thanksgiving,
