One more precaution: Don't use the anti-static alignment tools on these older sets. They are conductive, and I found out the hard way when using one to align the IF on an old radio, and touched one of the terminal lugs on the IF can. I kept getting zapped, and soon found out why. Besides, I found that they detuned the circuit slightly when inserted in the slug. Do yourself a favor and get the red and yellow plastic tools instead.
