In my Toshiba 27A33 27" CRT TV, there is a bipolar electrolytic capacitor that tests bad with a value of 6.8uf/50V. This capacitor is in the vertical deflection circuit. There aren't many options available for replacements. Digikey and Mouser have one option as a replacement but it specifies that said capacitor is specifically for audio and is only rated for 1,000 hours at 85C, (

Here is a link to the service manual page that shows a schematic of the vertical deflection circuit in the Toshiba 27A33 and shows said capacitor as "C442", (

Another site called "Arcade Parts & Repair" has a replacement but I'm not sure how good it would be, (

This Ebay seller has a new old stock replacement for sale by the Brand "Teapo", (

Which option would you go with? Would it be safe to create my own electrolytic bipolar capacitor by combining two polar capacitors to get the value I need and would it work well?
Someone on the EEVblog forum suggested that I use a film capacitor such as this, (
