Review BURLE Tube Type Amplifier Oscillator Nos

The Tube Burle Amplifier Oscillator 4657 NOS is a vintage electronic component that harks back to the golden age of analog electronics. This oscillator tube, manufactured by Burle Electronics, is a 12AX7 dual triode vacuum tube with the 4657 designation.

The 4657 NOS tube is a versatile oscillator, capable of producing a wide range of frequencies due to its dual triode design. It features two independent triodes, each with its own control grid, enabling the user to create complex waveforms or multiple oscillation frequencies simultaneously. This makes it an ideal choice for various applications, including audio frequency generation, test equipment, and vintage audio equipment restoration.

The Tube Burle Amplifier Oscillator 4657 NOS is a New Old Stock (NOS) item, which means it is a previously unsold, preserved, or surplus tube that has been stored in a safe environment since its production. This ensures that the tube maintains its original electrical characteristics and performance, providing a reliable and authentic performance compared to modern reissued tubes.

The 4657 NOS tube is a 9-pin glass envelope tube, with the negative (ground) pin located at the bottom and the positive (filament) pin at the top. Its filament voltage is 6.3V, and it consumes 70mA of power at this voltage. The tube's maximum rated plate voltage is 300V, and its maximum rated plate current is 120mA.

In summary, the Tube Burle Amplifier Oscillator 4657 NOS is a versatile and reliable electronic component that offers vintage enthusiasts and audio engineers an authentic and authentic sounding oscillator. Its dual triode design, NOS status, and its compatibility with vintage equipment make it a valuable and sought-after component in the world of audio electronics.
