Are these the same electrically


 

I think I know the answer (yes they are) but just need to see if I am wrong. Silly but RF is still part Black Magic.
One powers the circuit from the top of the coil and the other from the bottom. Power is "removed" at the center tap.

The circuit is from a 6M DSB Manhattan style transceiver.? MUPPET style really.

Much the same, except in the top circuit the VCC rail will be hot with RF (unless there is decoupling down the line that is not shown.)? In the bottom circuit, C6
will put the VCC rail at RF gnd, (assuming short leads, proper type of cap, etc.)

In the first example you have to also swap C39/C40 and C43/C44 to make it work.
Both circuits work in class-C and are not suitable for the actual DSB signal.
