They are/were called "high frequency non-polarized electrolytic" capacitors.

Because they are explicitly intended for operation in a horizontal sweep circuit, they are much physically larger than a "standard" non-polarized electrolytic capacitor of the same value and voltage.

Interesting. I replaced it with a beefy 3.3uf film cap. Do you think this could be causing the weird horizontal linearity issue?

For reference, it was like that when I had a bipolar electrolytic in there, before it blew up.
