— Schematic Circuit Diagrams —

Where possible I have redrawn the following schematics in the original style and layout so there may be a few inaccuracies, please let me know and I will correct them — Where components are concerned I have generally used common symbols for basic parts i.e. an electrolytic capacitor is drawn in the old British style and looks like where the shaded end is negative — The American symbol would be where the curved side is negative

I have elected to use the british symbol for redrawn schematics — Resistors are drawn which is common to nearly all older schematics and looks like a difficult path for current or even a heating element which is actually what it is! — The box symbol indicates nothing but I use it for the day job and some schematics that I produced for this site

Another area to look out for is junctions, most older schematics use bridges to show wires that cross later becoming a simple cross + — Junctions are often marked with dots — As a rule however drawn no more than 3 wires should meet at a junction — I have elected to use bridges or simple crosses with junction dots (often coloured differently) and more than 3 wires at junctions if it reflects the original style and is obvious what is connected
