Below, the front and back of a fold-out JMI brochure, early to mid 1961 - printed for "Musicland", Bexleyheath, Kent. Musicland was run by Tom Jennings's son, Paul. The only amplifier illustrated is the AC2, but prices are given for the AC30/4 and so on. A version of this brochure issued by JMI for general circulation gives the price of the AC30/6 - on the AC30 website.
