And sometimes vendors knowingly use undersized capacitors, so that they
will get burned a while after the period of warranty ended. This is a
known issue by German consumer centers. I experienced it for the PSU of
a Behringer mixing console. I was an engineer and can repair it myself,
or assumed I shouldn't have the needed equipment at home, a friend still
is working as engineer for a company and can help me. For this
particular PSU it was easier to do by hot air soldering. Sure, without
hot air the soldering isn't impossible, but already hard to do for
experienced engineers and perhaps impossible for averaged people.
Vendors design things to get broken after warranty period ended and they
also try to make things irreparable.
