Altec 288-C Horn Driver

Description

Here we have an Altec 288C driver in very good condition.
As shown in the photos, there is a + and - scratched into the housing below the binding posts.
See the photos for other minor cosmetic issues.
I have attempted to show the dimples in the diaphragm as clearly as possible; it was tested with a 1kHz tone
before being removed from it's horn. This unit was inside an enclosure so didn't even see much dust.
