[Boatanchors] Halli HA-5 vfo to Millen 90800 transmitter

[Ian Wilson]

Found the schematic here:
http://www.w8vr.org/VR_AlbumCover/VR_Album1/BigRig/Exciter/slides/Exciter%20Millen%20.html

According to that schematic, the crystal connects between g1 of the 6L6 and
ground.
And the cathode switch grounds the cathode (at AC) for use as an amplifier
rather
than an oscillator.
