• Anotaciones
• This radio comes from Portugal. So ist is very likely that it is an export-model. Due to information from internet it was part of the 1952-1954 export range. The "T" in the name of certan export models shall indicate that they were "tropicalized" to meet the climatic conditions of the destitated countries. The battery supply leads at the backside of the radio are described as follows: red = +90V, yellow = -90V, brown = +1,5V, black = -1,5V. Gerät stammt aus Portugal. Vermutlich Exportmodell. Laut Internet war es Teil des Exportkatalogs 1952-1954. Das "T" in der Modellbezeichnung soll "tropicalized" bedeuten, also ein Hinweis sein, dass Gerät auf tropische Bedingungen im Ziellend vorbereitet wurde. Die Kabel zum Anschluss der Batterie haben laut Rückwand folgende Belegung: rot = +90V, gelb = -90V, braun = +1,5V, schwarz= -1,5V
