Btw,  type 73 material is conductive, so you need to sleeve the core or use
wire  with a thicker insulation than enamal.  If you are happy to use  twice
the number of turns, then consider using 2843000202, you don't need  to
sleeve these cores as are non-conductive!

I have been using no.27 enamel wire with only the secondary within a teflon  
tube in the core. The primary is wound around the telfon but clearly touches 
the  bare core -- are you saying this is not good?  Pete  W2PM
