HMV early radiograms
Posted: Thu May 10, 2018 5:05 pm
When did British HMV start making radiograms? The firm made a prototype Lumiere diaphragm and crystal/two valve radio in 1924 (Proudfoot - His Master's Gramophone, Catalogue of EMI Collection and other sources) though the radio technology seems rather dated for that year, but apparently nothing else until the Model 520 that appears in their 1930 machine catalogue. Was there really a 5 year gap in their production of radiograms? Does anyone know of models between 1925 and 1930, or have catalogues in that date range that show any?
HMVs first electrical players (but not radiograms), Model 551, appeared around 1929-1930, along with the big Model 600, but was there anything else? I am trying to establish who made the first radio-gramophone combination, and when. First I suppose we need to define 'radiogram'. Victor produced cabinets with acoustic gramophones in and a space where an RCA Radiola or similar could be fitted (for the 1924-25 season) but this doesn't really qualify as a radiogram! Brunswick started advertising the Panatrope in late 1925, with built-in electronics from RCA, which obviously does qualify. But where were the Brits?
Thank you to anyone who can help.
