FT-2000 - Deaf as well?

I recently had a look under the hood of an FT-2000; and just as I’m done repairing two FT-897; I notice that the FT-2000 should be a suspect as well! Yaesu: what gives?!

You can see the same white oxide leaking out of the porous plactic of those filters.

A warning to FT-2000 users: you should check them periodically.
