Re: The BBQ and unpotting NST's

The best way is to put the NST in an oven at 150C, and leave it there for
1/2 an hour. If the tar doesnt melt, turn it up to 200C. again if it doesnt
go turn it up to 250. Put a tray under it so that the tar will drip onto the
tray, and then I use isopropyl alcohol (propan-2-ol) to clean the tar off
the rest - I just soak it for about 6 hours. Be careful though because if
your NST is made by Jefferson (I think) then the windings will be insulated
with tarred paper, which can come off when you soak, rendering the secondary

Good Luck!
