Estate sale find in old New Hampshire home

Did not power on so sold as is

No cracks or chips to the Bakelite case. Just needs a good polish to really shine. The knobs work as they should. The thick card board cover on the back is cracked. ( see pics ) The electrical cord appears to be in good shape

I peaked inside and all tube's appear to be there.

Possible easy fix but I have no idea.

Excellent candidate to restore to work  or display as is

Please review all pictures as they add to the detailed description
