Actually, L6 does connect to the signal path between the output of V1
and the input (grid) of V2 when switch S1B connects it. L6, like L3,
has two windings. I'm looking at the S-40B drawing.

Nick you are a joker..hi-hi,? as shown, L6 never gets any signal from
the left but is connected to the caps and tube as expected at the
right.. That switch looks clear enough on the drawing. ?Maybe the
drawing has some UV components and wires? I am looking on the BAMA pdf
doc.?? maybe the paper wore thin?

So the same would be true for L6...
Also, I wonder if under some circumstances (~1/2w antenna) shorting out
that 1k resistor would improve Band 1 performance.? Seems like it would
be a voltage divider the way it's configured in the schematic.? Unless
maybe it was intentional attenuation to stop broadcast band overload in
urban areas?
