Transistor divider organs

Transistor divider organs were manufactured by Wurlitzer in the 1960s and 1970s. This time period represents a boom in organ production, as there are many models and variations.

Integrated circuit (IC) organs

In the early 1970s, Wurlitzer began manufacturing organs with integrated circuit (IC) dividers. These organs are still analog, but their solid-state components are miniaturized into ICs. This allows the organs to pack more features into the same footprint.

Wurlitzer’s IC divider organs can be split into two main categories: beginner-friendly Funmaker organs, and the more professional Centura line.
