    The arrows point to the negative side. Also the side with the indent is positive on a axial cap.

    Quoted from ForceFlow:

    Not always. On some older caps, it's the opposite way.
    Here is a refurbishment guide for the power supply: http://www.pinwiki.com/wiki/index.php?title=Gottlieb_System_1#Recommended_Power_Supply_Updates_.26_Repairs
    You really should replace some of the diodes as well, as they were sometimes prone to fail, short out, and burn up.

    I have never seen an axial with the indent on the negative side. Interesting...
