Default Re: What is this 1930s Cabinet Radio?

The tuning dial is clearly pre-1935, and the radio section valves are of the earlier balloon shape rather than the shouldered shape which was introduced in 1933 (although they were available long after). I would be suspicious of the MU14 rectifier, as this is a high heater current + high DC output (120 mA) device - the two radio valves would have required no more than 50 to 60 mA, and it is possible that this rectifier valve was a handy replacement for an earlier one with lower output. Critically,though, at 2.5 A heater current, this may be overloading the mains transformer, since early 30s rectifiers operated with 4 volt 1 amp heaters. Pick-up sockets were fitted to some radios from the late 1920s so the set must lie within the period 1929 to 1934; knowledge of the valve line-up would help with the date. The post about Smith's clocks would suggest 1931 to 1933 as the period, whilst the dial appears to be calibrated not in degrees but in metres, suggesting 1932 - 1933 as the probable date.
