PlayStation 2 controllers not vibrating

Hi

I think there’s something wrong with my PS2:

My controllers aren’t vibrating!

I’ve tested 2 controllers on 4 games and I’m not getting any vibration! I hear the problem is a blown fuse, could be fuse 50 in the PS7 or PS9 section of the board. I intend to get a replacement but I see all these sites which have the parts for cheap prices but I’m worried fuses from certain sites may be no good, after hearing about the dialemma some have had over those bad replacement PlayStation 1 lasers. Aliexpress is one company I will NEVER do business with!

Where should I buy new fuses from? I also hear that multi tap support can be lost to a blown fuse, but I’m not in a position to rummage for my one at this time to test.

Thanks
