I am going to try LM2596 - 150 kHz DC-DC converter with 6C4C. I will let you know how it works (if it works at all).

40 kHz oscillator driving chip amp driving small transformer.

same way craig does it.  Easy, cheap and makes biasing

much easier.

 

Well we could use the Darkstar PCB's for something... ;D

Forget it, LM2596 doesn't stabilizied very well under 600 mA, so I didn't even try 6C4C.

Voltage in from 6,5  V to 7,5 V gave voltage out from 5,5 V to 5,8 V.
