Before you start assembly, check the board for etching faults. Look for any shorts between tracks, or open circuits due to over etching. Take this opportunity to sand the edges of the board if needed, removing any splinters or rough edges. (With the boards supplied by me, the edges are already milled, and etching faults are very rare.)
Line 192:
* 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.
