Gulbransen Rialto

Electronic theatre organ

The Gulbransen Rialto (Model K) was the company's best-known electronic organ and is regarded as the first electronic theatre organ. Designed to recreate the sound of a Wurlitzer-style theatre pipe organ, it used two auxiliary Leslie rotating speakers rather than an internal amplifier and speaker system.
