RC40 Wall Box
1957 BAL-AMi RC40 Wall Box
This is the ultra rare BAL-AMi wall box that can be attached to the Super 40 model, and maybe others.
This particular example, serial number 22, is owned by Tony Holmes and he kindly provided the photographs.
I have only seen evidence of four or five others in existence.
In April 2020, UK jukebox and amp restorer Bob Harper was given the task of bringing one of these back to life, and he succeeded! Possibly the only working example in existence.
