Heres another project of mine from last year, that i dug out, dusted off and fixed up.
A amplifier using jfets in the input stage and laterals in the output stage.
This amplifier is unique from my other projects in the sense that its dc coupled, which means there are no capacitors in the signal path to cause low frequency rolloff, instead this amplifier has frequency response down to DC.
The overall design is based off of several commercial amplifier topologies including D Self's "blameless" mixed together, and with some of my own ideas mixed in.
The overall schematic:
