  • There are two slightly different chassis. We call them Mk1 and Mk2.
    This later model employs the Mk2 chassis, the 1st IF-filter is above valve V1, and the 2nd IF-filter is above valve V2
    (The Mk1 chassis released in 1956, the 1st IF-filter below valve V1, and the 2nd IF-filter below valve V2.)

    There are some other minor changes, they are explained in the Trader Service sheet "1381".

    Battery or mains AC/DC. Price £13.12s. 11d. plus tax.

    Similar or identical chassis to the RGD B55 (RGD took over Regentone in 1950s before in turn being acquired by ITT/STC owners of Brimar, Schaub-Lorenz and Kolster Brandes). Compare very similar case Schaub Polo 9005 (different Chassis). Polo was later used as name for a range of ITT UK & Germany transistor sets.
