The JEI J73 console organ
Three manual, built-in 50 watt amplifier, late 1972 to 1975
The J73 was effectively the console version of the (just) portable Jennings J71 three-manual organ. For coverage of a J71, see this page.
The keyboard section could be detached from the base for greater ease of transport, a feature likely to have been copied from the Vox Riviera, which Tom and Dick Denney had helped design.
Below, the image of the J73 printed in the purple catalogue of later '73. Unfortunately, something went astray with the layout of this catalogue, and text relating to the Jennings J72 organ was given at foot (here omitted).

General characteristics of the organ were given in the most ubiquitous advert for the model, which appeared in both the popular and trade press in the mid 1970s:
