[QUOTE="Dave.m, post: 71927, member: 2828"] I am currently building a Surf P.I. 1.2 MD and would like to use a coil lead plug connector which i can connect different types of manufactured coils. Do all coil manufacturers use similar plug connectors and which pins do they use. I have used a coil basically as designed by J.J.Rogowski (B.B.Sailor) on Geotech 19 tuurns of .47mm enamelled copper wire, 10.5 inches diameter wrapped in two layers of PVC spirwrap with a layer of masking tape over the spirwrap coated with two pack clear auto paint mixed with powdered graphite (fine ground auto lube). A length of stripped copper wire was then mechanically attached and connected to ground on the PCB. The whole assembly was then encased in polyester resin. I haven't tested the unit yet as i fried the transistor in the power supply when i applied power. This problem I am working on at the moment. Any info any of the members can supply will be appreciated. Thanks Dave.m. :) [/QUOTE]
