Original poster: "Bill Vanyo by way of Terry Fritz <twftesla-at-uswest-dot-net>" <vanyo-at-echoes-dot-net> I'm just about to the point of re-assembling my depotted NST - I have a clean core and primary and secondaries. Will silicone cement (aquarium cement) work as a filler in the space between the coils and the core? Thanks, Bill Vanyo
