Ed, After watching all the hair pulling going on with this cap without resolution, I will offer to test your cap in my system. Cover the shipping to me, I will test it and even pay to send it back to you. I'm belting out some five footers with my 6" coil powered with a 6kva dry transformer and vacum gaps and a CP cap. If yours is good I should be able to swap it in and get similar results. Case closed. Glenn
