Jennings Electronic Industries AC15
Introduced in time for the Frankfurt Music Fair (Musikmesse) of March 1972, the AC15 was Jennings's second foray into the valve market - the first being the AC40, on which see this page.
From 1968 to mid 1971 JEI amps had solely been solid state. The move to valve was clearly driven by the market - valve was king.
Notice from "Beat Instrumental" magazine, April 1972 - the introduction of the AC15, a surprise item at the Frankfurt Fair - price: £68.

The electronics built lightly on a printed circuit board, the controls (potentiometers) soldered directly on. Not all that robust, but this one survived..
No schematic has come to light so far for this amp.
Its general appearance, the split level top in particular, is similar to many other small valve amps built by Rosetti and Triumph in the mid 1960s. It also resembles - a frivolous analogy - certain 1970s washing machines.
