Questo tubo è etichettato "R.M. (3,5V)", ma senza produttore. Poiché solo questo tubo della PTR ha una tensione di riscaldamento di 3,5 Volt, la foto dovrebbe adattarsi a questo lato del tubo.  <br />
Diese Röhre ist mit "R.M. (3,5V)" beschriftet, aber ohne Hersteller. Weil nur diese Röhre von PTR eine Heizspannung von 3,5 Volt hat, sollte das Foto zu dieser Röhrenseite passen.
