Lindsay, I'm not sure why but you keep getting confused. The 4.7nF is for the capacitor C40 coupling the anode of V3 to the grid of V4 (via the junction of R19/R20, actually) which you have been advised to change as your first priority.
I'm not sure what the problem is with C46, the cathode bypass, but that has a capacity of 47uF at 12V or greater and yes, it is an electrolytic capacitor.
The 4.7nF caps are not electrolytic and, therefore, will not have polarity markings and can be fitted either way round.
