Hi Vince, 
        I successfully used a pair this type with a 10/23 OBIT until I blew 
one out with exact resonance and no safety gap across it. With a safety gap 
across it, it should last a while but your resonant frequency will be quite 
high with this small a cap or your primary coil will be large.
