Discrete transistor line amplifier stage
Over the last couple of years most of my interest in audio has been with transistors. I've been slowly teaching myself to read and understand the circuits.
Circuits like this one for example. Not hard, but still a bit too complicated for me to understand without the helpful wikipedia markup attached.
Instead I've looked at primarily at the schematics I have for discrete audio preamplfiers, 1970's vintage typically. Based on what I've learnt so far, I've done up a "test mule" in LTSPICE, shown below.
It's not a circuit you should build. It's for pedagogical purposes, though it does actually work reasonably well - in simulation anyway. Its just a simple starting point to observe how the different parts interact under simulation.
