Removing the plate cap is another, but sometimes the lead drifts back to the tube and arcs.
Pin 5 is the first grid on most typical Zenith outputs like the 6LF6, but if you have a different output (not familiar with your model number), then you can look up the datasheet for the tube on line and identify the first grid.
