Why do preamplifiers have so many capacitors?

Saw the inside of a preamplifier, a higher model, and it had 8 to 12 capacitors. I know they are used to store Power and may regulate impedance. Are they dedicated to individual segments of the frequency curve or is it simply storing all the power to power dynamic needs of an amp whenever it's needed.  And some capacitors were bigger than others.

@jumia-

     Actually: what was supposed to be a link to the following Vacuum Tube Valley site and reprints, wasn’t, on the last reference.

                               You’ll find some good articles, here:

     Be patient, as you're downloading a complete magazine, in pdf form, for each issue.

@jumia-

        IF you are sincerely interested; the first few magazines/books/resources mentioned on the following link, are an excellent place to gain such knowledge.

         They were great to, "grow up" on and: even decades old, they're still fun to bring out and reread.

                          I miss the DIY/hobbyist PAPER rags!
