  • Notes

  • The 1934 Penta-Quester radio, announced in April 1934, was a high-tech marvel for hobbyists. It used pentode valves for superior performance and boasted a unique clock-face tuning dial for easy station selection.

    Technical Summary of the 1934 Penta-Quester Radio:

    Circuit:

    • Battery-operated, 3-valve superheterodyne design
    • Uses pentode valves for high-frequency amplification, detection, and class-B output (novel for the time)
    • Two tuned circuits with a high-frequency transformer

    Tuning:

    • Dual-gang condenser for band selection
    • Clock-face tuning dial with independent condenser control
    • Local aerial system with metal bars integrated into the cabinet
    • Other Features:
    • Table style cabinet with self-contained batteries
    • Moving-coil loudspeaker
    • Wood chassis with metal baseboard and sub-chassis wiring
    • Double tone control (one fixed, one variable)
    • Input volume control via variable aerial condenser
    • Differential reaction condenser for smooth control
    • Pick-up terminals for connecting an external source (e.g., record player)

    Overall:

    The Penta-Quester was a technically advanced radio for its time, offering high performance and innovative features like the clock-face tuning dial and local aerial system.

    It was a popular design among amateur radio enthusiasts due to its use of pentode valves and its ability to receive stations with strong signal strength and good selectivity.
