Yes.
He also mentioned that there is a fixed hard-wired tap on the plate coil which
the schematics doesn't show.
I am suspicious that whoever he got the plate coil from may have modified it
for use with a different transmitter and the plate circuit cannot be resonated
at his operating frequency.
The reason I had mentioned the possibility of the grid circuit being unable to
resonate was that before I got the schematic, I had thought that perhaps the
transmitter had a tuned-grid input circuit. It doesn't.
