Hi all
I have a problem with my brianGT kit: the chip produced flames and started smoking as soon as I connected the power. It's a dual mono configuration with 37 volts DC after rectification . So if anyone knows what I've done wrong: please let me know!

also (and I have done this once) the caps will build up enormous heat if they are put in the wrong way. Diodes go "pop", pretty loudly, but capacitors go "bang".
Don't people use fuses anymore? 🙂
I had a problem with diodes (the voltage rating), but nothing much happened because of the fuse...

Ok thanks for the quick replies, but I've allready found my problem (I hope)
Both PSU work fine and have a fuse😉 but the power entry at the amp box was poorly connected: v+ and GND measured 0 with an ohm meter so they probably connect somewhere.
One more question (for now): did I ruin the chip or does the internal protection work really well against stupidities like mine?

One of my chips has survived a shorted diode, so they are quite "robust". But some things will kill the chips - I don't know if your case is one of them.

If smoke and flames came out of the chip, then I would think it's probably toast.

Yes, one of the great quotes in all cinemaphotography (homage to Humphrey Bogart in "Treasure of the Sierra Madre"):
Fuses, we don. need no stinkin' fuses
muchos apologias to our brethren in Europe who don't get to partake in the cinema noire
everyone should get cameras ready when they start up their amps. it would be almost as cool as brianGT gallery!
good plan🙂 nothing lasts forever what if you go away and leave it on by mistake and it fails. better safe than sorry🙄
