An LTR cap is of great benefit with a static gap also. This
is because the LTR cap will keep the voltage lower on the
NST output. Over-voltage is a main cause of NST failure.
The matched cap size for your NST is probably about 12nF.
A good LTR size would be 1.5X larger than 12nF or 18nF,
for a static gap.
The use of an LTR cap lets you set the safety gap narrower
for a given spark output.
