What is the difference between a coil tap and coil split?
When I tap a coil I use several different methods. If I need an extra tap I have to install an extra eyelet in the bobbin.

I wind till I get to 7, 600 Turns and wrap the wire through the 2nd eyelet. Return the magnet wire from the 2nd eyelet to the coil and continuing in the same direction (top going) and add another 2,400 Turns. The coil now has a total of 10,000 Turns. My taps will be at 7,600 Turns and 10,000 Turns. Another way to wind a tapped coil is start with 5,000 Turns and add 2,600 Turns. You now have a tap at 5,000 Turns and 7,600 Turns. Tap example #1: 7,600 Turns + 2,400 Turns = Total 10,000 Turns 42 Plain Enamel Tap example #2: 5,000 Turns + 2,600 Turns = Total 7,600 Turns 42 Plain Enamel Tap example #1 gives you a stock plus an extra output. With the added output the coil also
