Let's hope that the leads to the power devices aren't too long and too thin and that the connectors at their board ends aren't too brittle.
That's also my concern but I couldn't find anything stronger. Any idea? The connectors are specified with 3A.
This time I used the 2.4 version of the honeybadger with 2.2pF LF to improve HF stability (among the other fixed issues).

Hi,
no connectors at all. Use wires of sufficient cross-section, 1.5 mm² for emitters and collectors at least, and solder them directly to your board.
Best regards!

Link to the schematic for the 2.4 version that you used?

There is also a list of changes with explanation. But I didn't increase the overall gain as proposed there, the other changes I took over.

The amp is working well, no oscillations
Hi,
don't route the +/- rail cables to your rectifier. Connect them to the electrolytics instead. That improves both performance in the LF region and hum rejection significantly.
Best regards!

Oh sure, what you see there is my quick and dirty test bench. And I will also order some proper caps instead of these small historical ones. But at first i have to perform some tests http://www.diyaudio.com/forums/solid-state/302263-test-cases-stability.html.
