 In the transceiver,​ only two kinds of valves are used: The quite "​exotic"​ double pentodes [[de:​PD120]] and power pentodes [[de:​PP226M]]. These two kinds of valves made by Tungsram in Hungary could be acquired even during war time to produce a sufficient number of sets: In the transceiver,​ only two kinds of valves are used: The quite "​exotic"​ double pentodes [[de:​PD120]] and power pentodes [[de:​PP226M]].
