Hi,
I am looking for a replacement transistor on Joker Poker. The one in question is the one under the field that controls the kings reset coil. Any suggestion what commonly available transistor would be suitable to replace the original? I got the tiny one on the lamp driver board.
Thanks

2N5884 will work too.
BigDaddy Enterprises stocks those.

You should always add the pull up resistor to them, it prevents accidental lock on if your grounds are floating. Gottlieb added them themselves on later games where they (still) didn't have enough driver transistors for the coils on their games.

Thanks for this info. My Kings were locked up on route... Replacing transistor and adding resistor!
