Does anyone know how to test ic's and identify them where is the best online electronic shop?

Knowing what a ic chip does in a circuit the one here in circuit controls commands of the tape control from a Revox A700 reel to reel. Anyone had any experience with reel to reel tape recorders especially Revox?

There's a German website that offers company logos to help identify chips:

I've found it useful on occasion.

As for the numbers, I agree with Kiteman, but the logos do sometimes help narrow things down.

You're probably better off checking the number on the back of the chip and googling for it.
