It was my own stupidity... I prepared speaker wires while the cover was open AND the amplifier was powered on, so a little piece of copper strand fell directly on the mosfet and those two sparked with a PRETTY loud bang...
Does a replacement one need to have the EXACT same specs as the blown ones? I only found 600v 40a 160W IGBTs in available stores... And some have a differente "schematic symbol" with that diode thingy
The specs don't have to be exactly the same, but sometimes the compensation of an amplifier is designed for certain device characteristics. I would pick replacements that have reasonably close characteristics in terms of input and reverse capacitances.

I found this one https://www.mouser.de/datasheet/2/196/Infineon-IRG4BC40U-DataSheet-v01_00-EN-1228577.pdf
Is has less Watt and a different symbol though... (There is a diode arrow missing I think)
What do you think?

The weird thing here is that GB20B60PD1 appears to be a TO-220 device. I can't find anything online to suggest it was also packaged as a D2PAK. Is this a TO-220 package modified by the assembler for SMD -- or possibly a case of mistaken identity?
That does look like a SMD version but you could fit the older TO-220AB
type IF it can be fitted to any type of heatsink behind the original one ( if there is a heatsink ) .
Thats a fast recovery diode as the IGMosfet is designed for SMPS .
Not all IGMosfets are standardized to one pictured display .
The one in your link might do apart from the lower maximum power dissipation -- it depends how hot it gets in normal working mode .
As far as minus a fast recovery diode it depends on the associated circuit which will have been designed for a FRD --

Thank you! That's a bit of information to digest. What would you think about this? https://www.st.com/resource/en/datasheet/stgp19nc60hd.pdf
EDIT: I tried to desolder the blown IGBT's (disclaimer, I have no soldering skills) and It's really impossible to get it off. The heat instantly transfers into the "heatsink" which is also soldered to the plate! I ordered a hot air gun and I hope it works with that...

The link you provided shows an IGBT which has a much lower maximum power dissipation than the original one .
I think I completely F---ed up the amp. Breaker trips when turning it on. Lesson learned: Be cautious while the device is running
Always use a bulb tester in series with mains supply when powering up a malfunctioning or suspect faulty amp.
