Difficulty finding electrolytic bipolar capacitor

[CRTguy]

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, (https://www.digikey.com/en/products/...CRokkOQwLBKlQA).

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", (https://www.manualslib.com/manual/22...page=23#manual)

Another site called "Arcade Parts & Repair" has a replacement but I'm not sure how good it would be, (https://www.arcadepartsandrepair.com...c-radial-df-5/).

This Ebay seller has a new old stock replacement for sale by the Brand "Teapo", (https://www.ebay.com/itm/14358705324...Bk9SR9C105qtZQ).


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, (https://www.digikey.com/en/products/...MR100K/5413238). Would this be a good idea?
