date: label: date made
content: ca 1940
notes: label: Description (Brief)
content: Tube coating is disintegrating and has mostly flaked off. Tube is identified as a VR-54, a double diode with 8-pin base. AKA 10E-11400. However, this specimen has only 7 pins with only a hole in the base for the eighth. The unit appears of similar size and shape as the ARDD5 tube. The maker's stampings appear to have been over-coated and are now illegible. Reference: https://www.radiomuseum.org/tubes/tube_vr54.html and https://www.radiomuseum.org/tubes/tube_ardd5.html.
