Default single gain stage?

If I wanted just a single gain stage... even maybe a darlington..

how do I hook it to a input transformer? and how do I work out which input transformers to use and values and such?

balanced would be easier.... smaller power supply and get rid of those output coupling caps.


I don't like the mosfet because of the input capacitance... unless I try a CFP design... but then I still need the input tranny to drive the BJT.
