For the record I had 3 days on my TWDLE before both magnets stopped working. Discovered it was a 4 amp fuse and replaced it but not before it blew twice more during the first game each time after being replaced.
Turns out I was using a 4 amp/250v rapid acting fuse instead of a slow blow. OOOPS! I'm a pinball newb and that was lesson #1 for me. I bought a couple 5 and 3's when I went back for the slow blow 4 just to have some on hand because I didn't know if fuses blowing was going to be a frequent or normal occurrence.
By the way, is it?
Oh well, everything has been great ever since that one incident. Love the machine.
