Luckily I realized this before the T_junction reached 125°C. Or did it.
I know regulators have over-temperature shutdown, I don't think op-amps have.
So, er, people with acrylic and wood cases, take note. Have some vents at where the heatsinks are, both for intake and exhaust (due to convection - rising hot air).
Strange thing is even with the top open and a bit of forced airflow, the regulators still get warm.
This experience is cautionary for me - I was thinking of putting a T-amp in a picture frame, transparent side facing up of course.
But then again, these Zhaolu DACs run hotter than my T-amps, way hotter.
It was only until Zhaolu D3 when they realized to bolt the regulators to the casing to use the casing as a heatsink, no more temperature problem ever since.
