Just about everyone has seen this. You can get a pack of 10 ohm resistors and all 10 will have a different resistance. They're all close enough to be used as a 10 ohm resistor.
With the transistors same thing, you can get 10 MJL21194's and they're all not perfectly synchronized. They're within certain tolerances as well.
The ultimate goal is to find ones that are matched to turn off and on at the same time. That way all 7 power winding's spikes will hit the battery synchronized all at the same time. It makes a difference when you're looking at those fast switching speeds. Matching transistors would be an advanced skill. You can have a great energizer without matching them, but when building a race car, we want everything as perfect as can be because like in a race, milliseconds can be the difference between winning or losing.
