TABLE OF CONTENTS In order to look at the interesting business of designing and building valve amplifiers, we will need some knowledge of electronics fundamentals. Unfortunately, fundamentals are not terribly interesting, and to cover them fully would consume the entire book. Ruthless pruning has therefore been necessary to condense what is needed into one chapter.
It is thus with deep sorrow that the author has had to forsake complex numbers and vectors, whilst the omission of differential calculus is a particularly poignant loss. All that is left is ordinary algebra, and although there are lots of equations, they are timid, miserable creatures, and quite defenceless.
If you are comfortable with basic electronic terms and techniques, then please feel free to skip directly to Chapter 2, where valves appear.
Unavoidably, a number of mathematical symbols are used, some of which you may have forgotten, or perhaps not previously met:
| a ?b | a is totally equivalent to b |
| a=b | a equals b |
| a ? b | a is approximately equal to b |
| a ? b | a is proportional to b |
| a ? b | a is not equal to b |
| a>b | a is greater than b |
| a | a is less than b |
| a ? b | a is greater than, or equal to, b |
| a ? b | a is less than, or equal to, b |
As with the = and ? symbols, the four preceding symbols can have a slash through them to negate...
