  • Anotaciones

  • The main visual difference btween the  Baby Q Senior and New Baby Q All Dry is  the cabinet style/colouring (single tone). The Trader 534 only lists later Mullard Octal for the Baby Q Senior though with US numbering (described as Mullard Amerty) and lists DK1 DF1 DAC1 DL2 for this New Baby Q. Before 1942 the Edge connect valves are unavailable. By 1946 Philips numbering used by Mullard: There are also some small component differences (listed by Trader 534 30th August 1941)

    Generally from 1939 DK1 DF1 DAC1 DL2 but from late 1941 1A7G 1N5G 1H5G 1C5G, then in 1946:
    DK32 replaces 1A7G
    DF33 replaces 1N5G
    DAC32 replaces 1H5G
    DL35     replaces 1C5G

    The edge (P8) and Octal valves/tubes are not base compatible but different production times and electrically similar. This occurs on many UK battery models between 1940 and 1945. Even in 1945 / 1946 the Edge connect types are unavailable and Mullard issues instructions on how to change the sockets from P8 Edge type to International octal and the list of Octal replacements. These changes are seen on Ever Ready, McMichael and others.
