once again, it's probably ambiguity in communications. there isn't
an inductor in series with the GTR, exactly. there's a pi network
from the input terminal with the following: a shunt capacitor to
ground, *series* inductor, and the input capacitance of the tubes is
the output cap of the pi. the GTR goes to RF ground , but there is
no series inductance in that leg.
at least that's what was shown in the set of 91-beta schematics i
perused at dayton.
