Wind and install transformers T4 and T9. T4 can be wound with either a pair of wires twisted
together at 8-10 turns per inch and then wound on the core, or with the pair of wires wound in
parallel. Either method will yield a suitable transformer. An example of each method is shown
in the next figures.
