Look what I have done to TDA2050

[Agung Kurniawan]

Feed it with ±30V when the maximum value was below ±25V. I cant stop laughing

I trying to play with some resistor value when I plug something in wrong direction, it explode...

Cool.   

Now try a reversed electrolytic.                                                                               (No, don't really...)

yeah, good idea..
that sounds like home pcb-based  firework

ha! i did this to a TDA2030 a few months ago, i think by having too puny a ground wire. it was inside an enclosure at the time, luckily.

I'm not surprised if that's the heatsink you used. That will probably only dissipate about 5 watts if you are lucky.

I run about 36v in mine using the GGG Tda20x0 power amp
running 4 ohm speaker did not get hot but used the chassis as heatsink (mylared of course)

i think maybe your running it with too low impedence load.   perhaps your  running at less than 4 ohms ?

Yep, I havent use a good heatsink yet. its still on breadboard for testing

yeah, Im using heatsink+chassis for my 100W power amp transistor. and they do the job very well.
Im using low cost audio woofer speaker rate at 250Watt 8Ohm. when I play with some low-pass resistor. it just explode suddenly.
