Description

Nicht zu verwechseln mit der selteneren E452.
Gemäss HT Schmidt gibt es in der Literatur viele unterschiedliche Aussagen über die E452 - aber über die E452T heisst es: HF-, Audion-, oder NF-Tetrode, wahlweise mit US5-Sockel oder mit 5-Stift-Europasockel (Babani, Brans-Vademecum, Röhrencodex, Prehled Elektronek, Illustrated History of Philips Radio Valves)
