[Rich Measures]

>I am beginning the process of winding some toroid coils that are going to be

>1500 watts but I figure to be safe I will use two sandwiched together.
>Questions:

>1. Do the two toroid cores need to be insulated from each other 

€  no

€  yes.  A suitable wrap is self-sticking tape.     It has no adhesive.  
.It has good RF properties and it conforms like it was paint.   Plymouth 
Rubber Co. makes the stuff.  .

€   Teflon is easy to  cut.    self-sticking tape makes a good cushion 
for it.
