What is the power source you are using in photo #2? Can you just hook it up to a battery?

These variable voltage power supplies were common in the 60's and 70's on work benches where they repaired car radios, 8-track players and other accessories. A car battery will also work but most people did not want a big heavy dirty car battery dripping acid on their work bench. A large 6 volt battery will work, a small battery will not put out enough current to make a good spark.
