+40db small signal amplifier

I have been looking into small signal amplifiers, aiming to design one to have about +40dB gain and a few 100 mW output, this is the result

For both stages the DC bias is for about 1.1V on the emitters, and currents of around 10 & 50mA. Each emitter has a feedback resistor to stabilise the stage gain. The overall gain is +40dB with a 50R source and load.

In my tests I have an input of 20mVrms giving an output of 4.3Vrms, or 380mW. Here's the breadboard

+40dB amp, input at left, +12V bottom, output right
