This is for 3 crossover boards. The boards are compatible with Rowe and Rock-Ola models and are easy to install. One says CD-100A, that’s a Rode, another is for Rowe but not sure if it’s for CD box or Records. Last is for a Rock Ola, for a CD box I think. All untested- got in auction with other juke stuff I wanted. Buyer to add shipping.
