Hi there.

I’m trying to repair a pocket piano with a not working speaker. The actual speaker seems ok when I feed it with an external source, so i suppose that the amplifier is busted.

Problem: TD7056AT is out of production.

Do you know any reliable source (possibly in EU) of the chip?

Or do you maybe know direct replacement part numbers?

Best

Unfortunately the TDA7056AT was discontinued in 2016 and there was no direct replacement part created by the manufacturer.

A search on Octopart might yield some distributors with remaining stock…
