One terminal of the volume control should be grounded. Is it?
The center terminal (wiper arm) of the volume control passes through a bakelite block capacitor, part (27) on the earlier 89-19 schematic, part (26) on the later 89-123 schematic. This bakelite block contains one .01 uF capacitor. The AF signal is then fed from there to the grid cap of the Type 75 tube.
