Shown on this page (awaiting photographs) are a couple of portable receivers from Ultra. The R784 was made first, and is an AC or DC receiver, that could also operate from internal HT and LT batteries. Covering MW and LW, it was a compact receiver that offered good performance. A matter of months later the same chassis with minor modifications was sold as the R786, more commonly known as the "Coronation Twin". This is a very attractive receiver with a cream front and bakelite cabinet with carrying handle. The similarities with the earlier R784 are obvious. The Coronation Twin represents an early attempt to increase the appeal of an item by associating it with a Royal event, in this case the Coronation of Queen Elizabeth II. A nice touch to the Coronation Twin was that the mains lead could be disconnected from the receiver, and coiled up into a receptacle behind a door in the rear panel. Unfortunately insufficient space exists in the receptacle for a modern three-pin plug, and as a result the mains lead is often missing these days. (Also, many people have permanently wired the mains lead onto the chassis inside the cabinet on safety grounds). On unconverted sets the mains/battery changeover switch is automatically operated when the mains lead is plugged into the chassis socket. The receiver features a valve line-up of 1C1, 1F3, 1FD9, 1P11, and metal rectifier type RM2. The receiver cost £13.10.4 +pt.
Awaiting photographs of the receivers for the text above
Shown here is the model U7961 from 1954. This set is an AC only table receiver, but it is obvious where design similarities have been incorporated to benefit from shared tooling designs and hence reduce costs, especially when compared to the receivers pictured above from 1953. The receiver incorporates an internal frame aerial wound on the back panel, but otherwise there is nothing particularly noteworthy about this receiver. Valve line-up was UCH42, UF41, UBC41, UL41, UY41 and the receiver cost £12.6.6 +pt
