Let me say first, an excellent article! But to pick a nit (at your request), the control elements of thermionic emission devices (aka Fleming valves, or in some benighted venues "tubes" ;-) are called `grids'. The first grid is usually called the control grid; some common devices have up to five grids. In apology, let me say that I learned my basic electronic principles using this technology for my active devices (bar some 1N34's) :-). -- Ross Alexander @ Athabasca University!alberta!auvax!rwa
