It’s a counter measure, to BS on $150 mains fuses.
I urge those here to use it and pass it on and post it up, every time BS is presented on the sound of AC mains fuses and their installed direction
@analogluvr roberttcan pass this on
If you don’t want to blow $150
Change your old crusty fuses that may have seen too many turn on cycles (pics attached), then do it with the same $1 fuse, not the BS $150 SR boutique ones, as they will sound the same and age just as fast.
Pics of fast and slow blo fuses that have seen too many turn on cycles over a couple of years.
