    Question Atari 7800 S-Video Mod Tantalum Capacitor Polarity Question

    Hi,

    I'm working on doing the Atari 7800 s-video mod found here: http://saundby.com/atari7800mod/7800...struction.html

    For C3 and C4 he specifies 1uF tantalum capacitors and I got the ones found here: https://www.digikey.com/product-deta...1833-ND/563936

    In the circuit diagram he doesn't specify the polarity of the capacitors and the description makes it seem like they shouldn't be polarized, but as far as I can tell all tantalum capacitors are polarized. I emailed him, but I have no idea if he ever checks that email, so I figured I'd ask here. Can anyone tell me which way around the capacitors should go, or if I got the wrong thing, or if the polarity markings on the capacitors don't matter in this instance.

    Thanks for your help!

    Edit: Looking at other similar mods that specify polarized caps show the negative side towards the output jack, so I think that's what I'm going to go with.

    Edit 2: That seems to work.
