My parts (output transformer) will be here shortly to fix the one really quiet Fisher I have and then I am have the caps done and from what I have found out, plastic the coupling caps will not be. I am likely to order V Cap Teflon's.
Ummmm....Volley?
Teflon IS plastic. In fact, it's about the most plastic plastic that plastic can be.
Or maybe Chris V has a new "natural" source of teflon - perhaps the noted teflon springs of the planet Cestus III?
