How to offer Habrausers equipment for free use?

Question

Iron

Good afternoon, ladies and gentlemen!
If something is wrong, then immediately apologize!
The question is this: I, for example, have such an amplifier lying around - Kumir 35U-102S / 1 . How can I notify the habra community that I can transfer it for experiments or other things, and not throw it away.
Tell me, what kind of Avito is there for these cases? I agree! I can post it on the Avito type, but how can I notify the habra community about the announcement?
But the offer is real. If anyone needs it, then gladly.
