content: Marked: on unit: "Goltone", on box: "Goltone 'Cub' / Selector Unit / No. R14/26 / 2/6 / Wavelength / 200 to 500 / Meters". A British coil-capacitor combination designed for the grid circuit of a standard detector. Two copper strips separated by a mica dielectric act as a variable capacitor in parallel with the coil. An adjustable knob permits the copper plates to be separated, thus varying the capacitance of the condenser and the resistance of the tuned circuit. Made by Ward & Goldstone, Manchester. In original box.
