Published ratings and characteristics promoted from the supplied Telefunken source where explicitly readable. Telefunken RE112 directly heated 2 V battery receiver triode usable as oscillator, transformer-coupled grid detector, AF amplifier and driver for RE402B output stages. The manufacturer specifies an anode voltage maximum of 100 V for the particular transformer-coupled detector application only; this is not established as an unrestricted universal maximum plate voltage.
