    With Fliptronics 2, Williams put the snubber diode on the Fliptronics board.

    It there any reason to also leave it on the flipper coil?

    Yes. So you don't blow out transistors or have the coil lock on when you flip it.

    Belt and suspenders.

    In other words it is a backup to the fliptronic board and can be left in
    place as long as the coil is wired correctly.

    Lloyd, the Fliptronics 2 board has the snubber diodes on the Fliptronics board. D17 - D24 serve the purpose of the diodes on the coil. That
    makes the coil diodes redundant.

    We have had a TAF blow out the coil driver transistors on a couple of occasions when the diode broke on the coil.

    But on Fliptronics 2 games, we have never had that happen.

    I have no problem leaving them in place. On the IJ that I am doing the playfield transfer for, some previous hacker did a horrible job of
    soldering the diodes.

    I was wondering if I could just clip them off.

    I always wondered why DE/Sega/Stern with their great (IMHO) computer controlled flipper boards did not include the snubber diodes on the
    board. I have had Whitestar systems blow IRL540's because of broken
    flipper coil diodes.
