The Jennings Electronic Industries (JEI) J71 organ
Three manual, produced from 1970 to 1974
Page in progress, January 2026
Detail from the catalogue of Summer 1973.
The Jennings J71 organ was the successor to the J69, much as the Jennings J70 was to the J68. In effect, the J71 was a J69 with "Walking Bass". A superb example can be seen on this page.
Spring 1970.

Not much seen these days, a JEI "Portable Electronic Organs" folder, the one in view supplied with a Jennings J71 three-manual organ, contents unknown, perhaps analogous to the folders compiled by JMI for the Super Continental (circuit diagrams, notes on operation, and so on).
