The 1G6G is a battery double triode for audio output. The two sections are rated for push-pull use and the input voltage between the grids is quoted as 48.0 Volts peak to peak. The anode load is given as 12,000 Ohms between the anodes and the input impedance is 2,500 Ohms. In this configuration the output power of 0.35W is achieved for a distortion of 4%.
The wide glass tube envelope is 27 mm in diameter and, excluding the IO base pins, is 77 mm tall.
