6DE7

      The 6DE7,10DE7 and 13DE7 have dissimilar double triodes contained in a miniature envelope.Here is about the 6DE7.Triode NO.1 is intended for use as a vertical deflection oscillator and Triode No.2 is intended for use as vertical deflection amplifier.
      What comes next is about the electrical data of 6DE7.The heater voltage is 6.3 V.The heater current is 900 Ma.Then is about the heater-cathode voltage (design maximum values).First is aout the heater negative with respect to cathode.The maximum total DC and peak is 200 V.The second is about the heater positive with respect to cathode.The maximum DC is 100 V and the maximum total DC and peak is 200 V.
      There are the direct interelectrode capacitances of 6DE7 (unshielded) to follow.The grid plate of Triode No.1 is 4.0f and of Triode No.2 is 8.5f.The input capacitance (g to (h+k)) of Triode No.1 is 2.2f and of Triode No.2 is 5.5f.The output capacitance (p to (h+k)) of Triode No.1 is 0.52f and of Triode No.2 is 1.0f.
The following is the maximum ratings of 6DE7 .The maximum DC plate voltage of Triode No.1 is 330 V and of Triode No.2 is 275 V.The maximum peak positive pulse plate voltage of Triode No.2 is 1500 V.The maximum peak negative pulse grid voltage of Triode No.1 is 400 V and of Triode No.2 is 250 V.The maximum plate dissipation of Triode No.1 is 1.5 W and of Triode No.2 is 7.0 W.The maximum average cathode current of Triode No.1 is 22 Ma and of Triode No.2 is 50 Ma.The maximum peak cathode current of Triode No.1 is 77 Ma and of Triode No.2  is 175 Ma.The self bias grid circuit resistance of Triode No.1  is 2.2 Megohms and of Triode No.2 is 2.2 Megohms.
