Vintage Dynatuner FM-1 Tube Tuner

CURRENT CONDITION:

General cosmetic wear but functions as intended.

FEATURES:

Tube-Based Design: Utilizes high-quality vacuum tubes (e.g., 6AT8A, typically uses a "magic eye" tuning tube) known for a "tubey" sound.

Minimalist Circuitry: Designed for superior performance with fewer parts, eliminating the need for extensive shielding, which contributes to stability.

No Oscillator Drag: The mixer and oscillator circuit design removes frequency drift when tuning, simplifying tuning and reducing interference.

Easy Assembly/Modification: Originally sold as a kit, the FM-1 was designed to be easy to build, and it allows for modifications like adding a stereo multiplex board.

Analog Tuning: Features a smooth, manual analog tuning control and an illuminated display, popular among vintage audio enthusiasts.

Stereo Upgradeability: While originally mono, many FM-1 units were later modified with stereo multiplex boards to support FM stereo broadcasting
