Hello all

I'm new to this kind of thing, so please bear with my ignorance.
In order to avoid smoke-powered computing I'm replacing all the electrolytic capacitors in this 40-year-old PSU, as they seem to be originals. However, the biggest such capacitor in the PSU is proving very difficult to find, and I only need two or three of them, not two or three thousand!
The casing has the following printed on it:
B43306-E0227-T
220 uf an1 +50/-10%
385V-
-40...+85°C 03.85
DIN 41238

Siemens doesn't seem to be making these any more so I'd be most grateful for any suggestions as to what would be a suitable replacement for it.

Thanks in advance for any help and advice.
