       | not gross. excellent level of information, explanation,
       | experimentation, teardown.

       | I still look at any electrolytics on a board with a bit of
       | suspicion, must be mild PTSD

       | Very informative. Needless to say that most "brand" capacitors
       | sold online from non reputable vendors are relabeled knock offs
       | that would exhibit inferior characteristics and last a lot less
       | than the real ones. There's no way you can buy a genuine Nippon
       | Chemicon or Panasonic capacitor on Aliexpress, but beware also of
       | unknown sellers on Amazon and Ebay. Always go to reputable
       | vendors (RS, Mouser, TME, Farnell, etc) to be 100% safe. The cost
       | of repairing a device that failed because of bad capacitors is
       | always higher than the difference in price of the real
       | capacitors.

         | Knock-offs tend to not pay for the patent licensing, but apart
         | from that both reliability and performance seems to match in my
         | experience.

         | I still wouldn't use them, but simply because if they _do_
         | explode in my customers hands, then my chance of suing some
         | noname brand for damages is low.

       | the process is not extremely difficult, but it turns out a lot
       | better if you use a clean box and keep the dust out when
       | assembling.

       | it is of merit among tesla coil buffs, to fab your own caps
