  • Scientific Two

    A battery kit-set introduced in 1931, described as “Simple, can be easily assembled with a screwdriver and a pair of pliers. No soldering.
    Although the new vertical, ribbed, six-pin plug-in coils had been introduced the year before (in the All Wave Four) this set continued to use the larger air-spaced coils dating from 1926. Almost certainly a ploy to shift old stock!
    The LH dial is tuning, the RH is reaction. The aerial coupling condenser is mounted on the LH rear of the chassis.

    Intended for use with open aerial and for reception of wavelengths between 15 and 93 meters.
    Three tuning ranges covered by plug-in coils:

    • 15-36 metres
    • 27-55 metres
    • 46-93 metres

    Regenerative detector, followed by transformer-coupled pentode valve. Directly connected loudspeaker. 
    Sold as a set. Price £4/5.
