Jim,
Don't toss them. the next time a neon dies, depot it, wind 12
or 15 turns of A.W.G 10 wire in place of each secondary. Connect these
new secondaries in parallel and connect each lead to a graphite brush.
With a little bit of mechanical work (chop sticks work well as a
visualation aid) you can get the graphite electrodes to heat 1.25" Cu
pipe to soldering temps. in seconds.
