In europe the for the resistor is a rectangle, whereas the US symbol is a zigzag. On my site, schematics may be drawn with european or US symbols, depending upon which of my circuit simulator programs has been used. Circuit Maker can use either european or US symbols, but I use Circuit maker with US symbols.
The top symbols represent vacuum tube or thermionic devices. Although at one time, these were being replaced by the smaller transistor and integrated circuits, they are finding their way back into electronics for use in professional audio equipment and some radio receivers. I would like to point out that the demise of thermionic devices was not due to poor performance, it was because of the physical size, weight and power consumption when compared to transistorized equipment. Also the US symbol set has a circle around most active components, whereas the european symbol set does not.
