Rock Ola NEw Old Stock remote volume box. These will work on many newer Rock-Ola 45 Record Stereo jukeboxes from the mid 1960’s on up. Check your manual. Some require a special 5 pin plug on the amp we don’t currently have available, and shielded wire. These are new but been on the shelf for a while, some have shelf wear, we will ship the best looking ones. The back cover is included, but has been removed for a good clear picture of the inside. Rock-Ola Part 52125-A
