A couple of comments on the schematic diagram:

1.  The symbol for the PM12 screen grid RF amplifier tube shows an extra, extraneous, grid ... not shown as connected to anything.

2. The "S / L" wavelength switch and associated coils shown connected to the screen grid (pin #1) of the PM12 should probably be shown, instead, connected to the junction point of the two 0.0003 uF capacitors and the tuning capacitor in the detector (V2 / PM2DX) grid circuit.
