Hello I'm sound system owner in Jamaica however i bought a couple of amplifiers that uses 4 driver I.Cs each. These I.Cs are labeled IOR with a logo similar to the logo on the IRS or international rectifiers chips after doing come research I found out that these I.Cs are the fake Chinese I.Cs. I also attached some picture of the I.Cs and the amplifiers schematic if this can help you to assist me plz?

However my question is if I should buy some genuine driver I.Cs and install them would my amplifiers be able to work just fine?

Also if the pin layout in my amplifiers schematic is identical to the irs2092 chip pin layout does that mean that these two chips are the same?

How can i match two I.C to find a genuine stable replacement?

When I Google the number on the i.c only aliexpress results are found and these i.c cause the DDT light on my amp to activate and mutes the amp it doesn't matter how low the input signal is and the active lights doesn't light up either. When I replace them the amp works fine for a couple gigs then the I.Cs fails again so I'm trying to find a good replacement.
