Hi all,

I'm thinking of building a preamplifier circuit for my epia carputer and I came across this one.

I imagine the circuit may need to be modified a bit for the epia line signal level and the reduced supply voltage, but I think something like this would work out quite nicely for boosting 1) the low output signal of the epias to about 4 volts and 2) improving the poor low frequency response I currently have.

If anyone has any suggestions on how to modify this circuit I'm all ears, otherwise this is going to be a bit of a learning experience for me.
