DualRatedFlyer Posted October 18, 2021 Report Posted October 18, 2021 I had a cap blow in a Aeroflash power supply for the tail strobe and need a replacement. Anyone happen to have a Whelen 490TCCF or Aeroflash 152-0007 they would like to get rid of? Pictures for reference. Quote

"Failed on its on" is the most common mode for high power electrolyte caps, they used to come in sockets on amplifiers for that reason. Exposing them to hot/cold weather variations adds to the mortality rate.Sent from my Pixel 3a using Tapatalk Quote

Probably exposed to the most significant of situations you described. Quote
markgrue Posted October 18, 2021 Report Posted October 18, 2021 I have a new one I bought several years ago but decided to go to Led. Let me know if you are interested Quote
carusoam Posted October 19, 2021 Report Posted October 19, 2021 @DualRatedFlyer see Mark’s note above… Otherwise… check in with your local avionics guy…. Capacitors don’t last forever… so they can usually be pretty easy to swap out… Best regards, -a- Quote
