Description
Quartett EL34 Tesla OO-Getter (NOS typ), Ip and gm matched quadAlle Röhren wurden exakt nach Hersteller geprüft bei Anodenspannung 250V, Schirmgitterspannung 250V und Steuergitterspannung -12,20V. 100mA Anodenstrom und 11,0mA/V Steilheit sind gleich 100%.Auf dem Röhrensockel ist der erste Wert der Anodenstrom in mA, der zweite Wert die Steilheit in mA/V. Darunter der Gitterstrom in µA.Die EL34 spielten zum Test in meinem PP Verstärker (AB Betrieb nach Mullard mit Ub=430V) einwandfrei.Rö. 1: 94,5mA / 11,1mA/VRö. 2: 93,0 mA / 11,6mA/VRö. 3: 96,0mA / 11,7mA/VRö. 4: 96,5mA / 11,2mA/V Ip and gm matched quad EL34 Tesla OO-getter (NOS typ).All tubes were tested exactly according to the manufacturer with plate voltage of 250V, screen grid voltage of 250V and control grid voltage of -12,20V. 100mA plate current and 11,0mA/V gm are equal to 100%.On the tube base, the first value is the plate current in mA, the second value is the slope in mA/V. Below this is the grid current in µA.When tested in my PP amplifier (AB operation according to Mullard with Ub=430V), the EL34 played perfectly.Rö. 1: 94,5mA / 11,1mA/VRö. 2: 93,0 mA / 11,6mA/VRö. 3: 96,0mA / 11,7mA/VRö. 4: 96,5mA / 11,2mA/V
