Some matching transformers don't require the 300 ohm wire to be stripped at
all. I don't know if they're still available, but basically, the flat cable
went between two screws. The screws had a "star washer that was shaped like
an inverted bowl. When the screws are tightened, the sharp part of the star
washer would pierce the insulation on the cable and provide a connection to
the inner wires.
