Here's what the June 29, 1940, ATA/ARA instruction book has to say
about L-2:

"C-39 (across L-2 in the 190-550 KC receiver only) serves to tune
L-2 to a frequency lower than 190 KC, and by so doing increase the
amplification of signals at the low frequency end of the tuning range.
This assists in producing a reasonably uniform receiver sensitivity
over the tuning range.  The plate to screen capacitance of the RF
amplifier tube, Type 12SK7, and the wiring capacitance to L-2,
perform a corresponding function in all other receivers."

That, no doubt, would be the explanation that Dr. Drake would give you.
