Hi
Any IF deck that ever has had backwards orange drops in it is ruined
for all time. Send it to me immediately for disposal.
If you take a look at some vintages and builds of IF decks you will
notice that some have all the caps in "right" and other builds
apparently didn't pay much attention to the outer foil at all. I have
never been able to tell a difference between one and the other. The
radio will work just fine either way.
