Description
E.F. Johnson (2) ganged Dual Section air variable capacitor assembly Total Capacitance is 57 to 830 pF Total 3500 Volt
E.F. Johnson ganged air variable capacitor assembly. Consisting of two premium dual-section capacitors precision-synchronized via dual meshed brass gears, this unique configuration allows smooth 0 to 100% full-mesh rotation with a single 1/4-inch drive shaft. When wired together, the sections provide an expansive combined capacitance range from 57 pF minimum up to 830 pF maximum. Designed with an industrial-grade 1/16-inch plate spacing, it delivers a reliable 3,000V to 3,500V (3.5 kV) peak voltage rating. Measuring 9.5" L x 2" W x 4" H, this high-voltage tuning unit features rugged ceramic standoff insulators and a rigid frame, making it the perfect upgrade or replacement component for high-power linear amplifiers, broadcast transmitters, and custom antenna tuners.
