There
are two main types of amplifiers, valve and transistor .They both
have their advantages and disadvantages .Valve amps such as Marshall,
Peavey, and Vox are often favoured by some guitarists for their
character of sound. They do need regular servicing or check ups, and
the valves may need changing from time to time. When changing the
output valves it is important to check that the bias is set up
correctly for the new valves. For one good book on valve amps (that's
"tube" amps to Americans!) I suggest you try:

Transistor amplifiers have longer life if they are well designed, are more robust if looked after but don't quite have the same sound.
