Years 1964 - 1971: The previously visible mechanism was hidden step by step. First it could be seen through a small window, later it was completely covered by the title glasses. First attempts with transistorized technology was done in the mid Sixties, but Rock-Ola returned to well prooven valve technology for another couple of years. The selection system was still electro-mechanical using numbers and letters.
