This is a Bipolar and FET AMP Circuit that I designed.
The little circuit will run big speakers at low volume and has a idle current from 35ma at 3.5volts and 220ma at 5volts.
The FET's stay cool under 5volts
The preamp that is a 2N3904 Bipolar NPN Transistor, this drives the N channel FET.
This sounds pretty good but don't go too high on the voltage or you will cook the FET's.
can you send me the schematics or post them online
