BA11 power filter

I'm not sure if you're talking about the same sort of device I had trouble with, so FYI: the Pro power supply is a box the size of an old-fashioned Bible, with a CEE power inlet at one end. That inlet is actually part of a sealed metal box containing a power filter. Mine decided to let out its magic smoke, in quite spectacular fashion, stinking up the workshop and leaking evil looking black tarry stuff over the insides of the power supply. But the supply appeared to be intact in other respects. I couldn't find a matching filter, so instead I found a functionaly similar filter that's physically smaller. I then created an adapter plate with a hole to accept the new filter, and a flange sized to match the old one. My sheet metal skills aren't great so it doesn't look all that professional but it's plenty good to get the job done. FYI, the new filter is this one: https://www.digikey.com/en/products/detail/schurter-inc/5120.2006.0/1843934 -- about half the size of the one it replaces.
