Perhaps this is a picture of the amp that is missing from the OP's console. I believe it is used to drive external satellite speakers in stereo while the radio chassis' on-board amp drives the console speakers as a mono center channel. I think the radio will work without the amp but not the turntable. However, I think the turntable wiring could be modified to use the radio's P/U (pickup) input in mono. I once had a similar Telefunken console but the separate stereo amp was mounted within the cabinet and the controls were mounted above the radio dial.

Here is an ARF discussion about this console.
