Mazda triode valve

Mazda triode valve

Mazda triode valve, UU5; a classic Mazda indirectly-heated HT rectifier with a characteristic envelope shape. One side of the heater is connected to the cathode. The anode cavities are each made from two black pressed plates. This rectifier is designed to work into a maximum reservoir capacitor of 8 µF.

The UU4 (350V) and UU5 (500V) were used in larger radios from the mid-1930s and remained in the lists until the 1960s. (National Valve Museum website)

Mazda pentode valve

Mazda pentode valve

Mazda pentode valve, AC/PEN from the National Valve Museum:

The Mazda AC/Pen, introduced in 1930 on the B5 base, was the first technically successful indirectly-heated power pentode capable of enough output to drive a moving-coil loudspeaker at good volume. The envelope contains a bright cylindrical anode with clearly visible grids. The electrodes are held in, or clamped to, a glass pinch, from which wires will run to the spring base pins. The Mazda AC/Pen was the landmark valve whose design overcame these difficulties at low cost and without causing other problems.

Mazda pentode valve SP 41 from National Valve Museum

Mazda pentode valve SP 41 from National Valve Museum

Mazda pentode valve SP 41 from National Valve Museum: The SP41 is an amplifier pentode with external metalisation as shielding. The original design was from Mazda, and other manufacturers copied this successful design after it had become established. The demand for efficient video pentodes for TV came a year or two earlier in Britain than elsewhere and the SP41 was Mazda's solution. Shorter leads to shorter pins, and compactness in general, are essentials where high gain-bandwidth product is a requirement.
