Thanks! Very clever approach to save space.

Is that a dual-winding transformer?

alex, wow, neat design!!

very definitely.
There are two advanatges to inverting the L angle.
1.) the heat transfer interface is moved down towards the optimum height for heat dissipation (~ 40% up from the bottom)

2.) The output devices can be mounted much closer to the heatsink, significantly reducing the thermal resistance of the thin horizontal leg of the L.

There is a small advantage to mounting the To3s on the outside of the L. The inside face will be non-flat and extremely difficult to be corrected to flat. The outside face of the L is also likely to be non-flat but these faces can much more easily be corrected to flat, or at least flat enough.

Might as well throw the pictures in here as well.

This is my first prototype of a headphone amp, only one channel atm. Still learning the ropes of solid state. Amp does work fine after all the kinks were worked out.

Running only 2n3904/2n3906 and MJE3055/MJE2955. Will try other alternatives in the next version.

Thats good... did you use Diptrace to do the PCB by any chance ?

Very neat
