Hi there

The circuit developed nicely with help from a few friends - I am very happy with the sonic results. To put is plainly the sound is the best I heard from my cans EVER!

Here it is - the (DEWAUDIO) MINIMA SE, CLASS-A, H-AMPLIFIER.

Here is my project exicuted on Veroboard. (I hate veroboard but it works for this job)

The circuit is fully class A and the output transistors gets extremely hot!
Power is currently supplied by a 12v battery but I am working on a propper regulated PSU for highest fidelity.

Later I would like to do a popper PCB as well in a neat cabinet.

(NOTE: Current transistors used in the Veroboard unit is SJE5300's from Motorola mounted in old CPU heatsinks for a LAN switch)
