These new display boards are direct replacements for Rock-Ola boards 52030-A and 52035-A found in the MAX series of Jukeboxes that were manufactured by Rock-Ola from 1979. The original Rock-Ola Vacuum Fluorescent Displays fail over time and replacements are not easily obtainable. The new display boards feature LED display technology and are direct drop-in replacements for the old-style displays. Additionally, the new displays can be used with the original display driver IC (MM57163N) located in the Profit Setter Module.
Note that in a lot of cases the MM57163N chip itself is also faulty and for this reason, it is included in the Kit.
(The MM57163N is also available separately)
