in the late 90's - early 00's some guys in Taiwan stole the capacitor electrolyte recipe from Panasonic (the largest manufacturer of capacitors). They started manufacturing them at a massive scale in china for undercut prices. Every major company bought their capacitors and re-branded them as their own.
They forgot to steal the recipe for preservatives...
It is why almost all electronics from that era are absolute garbage. It's why your TV, blender, coffee maker, computer, TV remote, washer and drier, dishwasher failed after a few months
Radioshack doesn't sell a lot of capacitors anymore, so they are probably the same ones from that era.
