Low Voltage Preamplifier by BC549

A low voltage preamplifier optimised for 3 Volt operation.
This is a special low voltage version of my audio preamp. T1’s emitter voltage is biased close to half supply voltage (1.5V) to allow for maximum output voltage swing. Both transistors are direct coupled and have closed loop feedback to aid temperature stability.
