Siemens v276 choke replacement

I'm in the middle of swapping some components in this vintage Siemens V276 clone (Techfilm WM-1) because there's too much audible white noise on the output.
One of the chokes seems to be damaged so I'd like to swap it out too, but I can't seem to find a specification either for the Techfilm WM-1, or the Siemens v276.
I know they should only block higher frequencies than audio... but could someone maybe help me to find a value that's not too wrong? 🙂
