      It is still working after all this time. There is probably not that big of an advantage having diodes in parallel like that.

      @@malvargeronilla3502 If it is the same problem, make sure you remove all the bad diodes and leave only good ones. In theory the total current of the diodes should be added, however they are never exactly the same, that means some diodes will do more work than others.

      Diodes in parallel are usually not a good idea, when they get warm only one of them does most of the work anyway.
