Shape	Tablemodel, with any shape - general.
Dimensions (WHD)	200 x 150 x 170 mm / 7.9 x 5.9 x 6.7 inch
Notes	Battery setup: "A" battery for filament heating: Four to six 1.5 volt dry cells connected in parallel. Good batteries are recommended, having approximate dimensions of 2.5 inches diameter by 6 inches high. A two volt (one cell, lead type) storage battery may be used instead. "B" battery for supplying power to the plate circuits, consisting either of two 22.5 volt plate batteries connected in series, or one 45 volt plate battery. "C" battery for producing a negative grid potential, consisting of one 1.5 volt dry cell. This may be conveniently the same as one of the cells of the "A" battery and this is recommended. The WD11 were often replaced by UX199, using adaptors. 60 mA from 3 V made only 0.18 W per UX199, while the WD11 drew 0.25 A from a 1.5 V battery = 0.375 W, practically twice as much. The price was the same: 6.50$. Supplementary Amp.: Radiola Balanced Amplifier.

Gerhard Härtl 15.Sep.07	1 rca: Type RI (ri); Radiola III (3) Hallo Radiofreunde Ich möchte meinen Radiola III einen Verstärker nachschalten an die Hörerbuchsen. Was für einen Übertrager könnte ich da verwenden,eventuell einen 100V Ela-Übertrager. MfG Gerhard Härtl
Konrad Birkner † 12.08.2014 15.Sep.07	2 No subject Sollten Sie den Originalverstärker nachempfinden wollen: Die Originaltrafos besitzen ein Übersetzungsverhältnis 1:3; Impedanz: Primär 10 kOhm, sekundär 90 kOhm; beim vorliegenden Trafo bei folgenden Windungszahlen: Primär 4000 Wdg, sekundär 12000 Wdg mit Mittelanzapfung (Gegentaktstufe). Kern ähnlich unseren M-Schnitten, 47 x 43 mm, Dicke 13 mm. Dies für den Fall eines Nachbaus des originalen Gegentaktverstärkers. Zur Ansteuerung eines "normalen" Verstärkers eignet sich jeder NF-Zwischenübertrager. Aber auch RC-Kopplung funktioniert, allerdings nur mit kleinem Aussenwiderstand (ca.10 kOhm). Auskopplungs-C je nach Eingangswiderstand des Verstärkers. Masse beider Geräte verbinden, je nach Speisung auf Potentialfreiheit achten. Sicher geht auch ein Ela-Trafo, er dürfte aber hoffnungslos überdimensioniert sein. Viel Erfolg!
