I’m looking for away to amplify the audio signal coming from my
computer sound cards output.
I’m trying to amplify the output voltage to 31 volts and the output
current to 1.5mA can someone recommend a small amplifier to do the job
or a circuit that will do this for me.
I'm just trying to do some testing.

31 volts * 1.5mA is 46.5 milliwatts, so if your sound card puts out
more than that just connect a transformer to it with the turns ratio
selected to give the output voltage you want into the load.
That would be a simple solution but try finding such a transformer these
days.

Wind it.
