I only dared to push them up to 2.5A, still no match.
I feared launching them into orbit, so I stopped there.



Why? There's no thermal runaway. As long as they don't get too hot,
they'll
be OK.



I observed a slight increase in current with temperature, and my
heatsink was only 0.6 K/W ...... ;-)

They specifically have a negative temperature coefficient. Interesting
experiment to push it

Still didn't sound like the Hitachis, though.

Please remember that this experimental amp didn't have AC loop
feedback (just a DC servo loop).
