I want to build an amplifier for my monacord mce 4000 electret mic.
Anybodey got any idea on how to do it?

do you mean a PA-style amp, or a preamp? two rather different things....

Have you tried looking up amplifier design? Do that first, then ask specific questions once you understand what you're trying to do.

The 386 audio amplifier is one of your best bets, good quality audio sound, simple to implement and powerful enough to drive up to a small 8 ohm speaker. Better than any dodgy transistor based preamp.

I guess he means preamp, but who knows.
The mic picks up sound poorly now so a pre amp should fix that right?
Forgot to say that Im going to use the mic for my pc

Most soundcards take an electret mic direct and supply power and all.

Let's back up a bit then...
A typical PC has a mic input.
A better-equipped PC (or sound card) has two jacks for sound input: the mic jack and the line-in jack.
Some setups have one jack that functions as both, and you select which way you want to use it in the sound card's settings.
The mic jack already has a pre-amplifier "in" it, so that you can use plain condenser mics with the PC just by plugging them in.
The line-in jack needs "line-level" sound, as it does not have an amplifier built-in. Things you usually connect to it already have amps of their own built in to create the proper line-level signal. If you plug a regular condenser mic into it and record from the line-in jack, you will hear a really really faint sound, if you hear any sound recorded at all.
This page shows how to build a one-transistor pre-amp for a PC condenser mic:

It would be good to make the amp's power adjustable, since you don't know how much will be useful. Too much is bad and results in a problem called "clipping".
Search Google for "digital audio clipping" for more info on that matter.
