Default Re: Denco coils substitute

They were jolly handy little coil formers - we used them by the hundredweight when I was an apprentice to L.O. Sparkes in the 50's. It is easy to wind similar coils on some suitable tube, but the biggest hurdle is arranging the B9a plugs, if you want them interchangeable.
