Specifications of a Pleiades 2 open base transistor long tailed pair microphone booster preamplifier

It should be small like a cigarette packet so as to fit inside a pocket. There should be no edges or protruding switches etc so a Bulgin vandal resistant switch is used. It should be self contained with battery and lightweight. Power consumption should be rediculusly low. It should operte in class A but the trnsistors left open base to self bias themselves with low current for low noise?, high imput impedance? etc. It should therfore be very linear at very small mic signals and progresively non linear at higher parts of the signal waveform in order to hve edge nd bring out the detail of music, singer, sax etc. Everything inside should be neat and beautiful and the box may be made of transparent plexiglas etc. Input and output should be traansformer balanced and isolated. Beautiful ring cores should be used for such transformers. There should be no capacitor, no resistor. Miou. It may be called Pleiades open base BC109c long tailed pair. Schematic should be engraved on top of box and is public doamin. Connector may be female nut secured DIN 3 pole. Transistors may be pluged in on IC type base terminals. It should be fun to make at home, beach, forest etc.
