I have an old Brown Brothers base that has both the paddle and straight key on
it. On the underside I put some plain old 1N40XX diodes and can use either on
the K2 with no changes and a single cord and plug.
HINT, HINT.... I sure wish this was an option on the K3 too. I often wondered
why such a great feature went away on the K3.
