Default Pre amps???which one???

Hey all,

i have been working on a portable amplifier for a school GCSE project for several weeks now, in several publications i have read about Pre amps and there aplication in such devices.

I am unsure of how to go about selecting a suitable method of doing this or applying this into my circuit.

I would be grateful if someone could send me some information regarding this subfect.


Thanks

Are you talking about a separate pre amp or one to go in the same case as the amp?

What power supply will you use for the pre amp?

Are you sure you need a preamp at all? In many cases an input selector and volume control is all that's needed.

Best regards,
