The 10P14 is an audio output valve designed for single end use in universal mains receivers. The 100 mA heater clearly identifies that it was aimed at equipment that used a few valves, like a radio receiver. we also have the 20P3 that is itentical except for a 200 mA heater.

The Mazda valve was designed after the time when Mazda gave up their own version of the octal base and adopted the International Octal.

The cathode resistor was designed to be 180 Ohm and the anode load to be 3700 Ohms.

The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 54 mm tall.
