Murphy Radio Model A186 From 1951

The last baffle table set built by Murphy was introduced in 1951. Shown above left, the model A186 still looks noticeably similar to the A122 and A122M from 1947 and 1949, but incorporates a few extra features such as the 6M1/(EM34) magic eye. It was built in both the Welwyn Garden City and Dublin factories, but was essentially similar. Differences included the fact that the W.G.C. version had three core mains cable as against two core from Dublin. The Dublin version did not have a frame aerial. More interestingly the W.G.C. model had an I.F. frequency of 465 kc/s, whereas the Dublin version had an I.F. of 470kc/s. There were also various minor differences in component values. The Dublin built receiver cost about a £1 more than the British built receiver. A radiogram version, model A186R, was built at the Dublin works, however there was no equivalent model from Welwyn Garden City. Like some previous up-market Murphy models, each waveband had its own tuning scale on the tuning glass, with an individual cursor and dial lamp. The card back (below left) had a frame aerial wound on it for local reception. Valve line-up is 6C9, 6F15, 6LD20, 6P25, UU9, 6M1. (Kindly donated).

Also introduced was the A188C baffle console model. This model was exhibited at the Festival Of Britain exhibition, and stayed in production for quite some while. The next console receiver (ie not including a gram section) was not to be introduced by Murphy for another five years, when the A272C was introduced, though still using the baffle principles.
