820/16 is the closest standard value.

I find modern electrolytic caps caps are low in value, close to their rated -20%, whereas the old Spragues were +100%/-10%.
I use United Chemi-Con EKYB250ELL102MJ20S 1,000uF 25V in Tek scopes.
I recommend to upsize to 1,000uF as the 2235A did. I believe your power supply is similar, here is spreadsheet with those cap details and sizes, taken from thread: https://www.badcaps.net/forum/showthread.php?t=71125
