[ARC5] Shunt vs. Parallel

[Richard Knoppow]

    I think you mean shunt vs: series, shunt and parallel are the same 
thing. The main reason for shunt feeding is to get the DC out of the 
plate tank. This is done in receiver RF stages to allow higher Q 
inductors. For instance, the main difference in the Hammarlund Super-Pro 
200 series that covers above 20Mhz is shunt feed of the RF stages. I am 
not sure what advantage this has for a transmitter. Shunt feeding 
requires a choke to act as the plate load which feeds the resonant tank.
