The Murphy A212 is a British four-valve table radio introduced in May 1954 by Murphy Radio Ltd of Welwyn Garden City, Hertfordshire.
It is a fine example of post-war British radio engineering, featuring an unusually styled wooden cabinet, a large loudspeaker and reception on long, medium and short waves. The 6P25 output valve drives the large 8-inch speaker. The set uses a conventional AM superheterodyne arrangement with an IF of 470 kHz.
Valves:
- 6C9: frequency changer (mixer and oscillator)
- 6F15 or 6F16: intermediate-frequency amplifier
- 6LD20: detector, AGC and audio amplification
- 6P25: audio output valve
- Metal rectifier: HT supply rectification
The service manual for this radio is available in the Members’ Area.
