=== Notes ===
* PCB is 6" long, mounting off pots at 3/4" centers.
* All type B boards that do not have a revision number have an error. Physically between the two BC557s on the PCB is a 47k resistor. This should be 470k, and will solve problems some of you are having with the common pulse out. Electrically it forms the upper leg of a voltage divider connected to the emitter of lower transistor in the Common Pulse out circuit.
