When you say "at cap #67," do you mean the side connected to the plate of the 7C6, or the other side connecting to one of the 41 grids and the tops of resistors (68 ) and (69)?
With no signal (radio not tuned to any stations), check the waveform at the control grid of the 7C6 (junction of cap (51) and resistor (60) ).
