Description

      YL1070  is a kind of double tetrode.It is used as linear single side band amplifier.It is composed with C.C.S and I.C.A.S.The frequency is 7Mc/s.The Va of C.C.S is 1000 V and the W_OPEP is 141W.The Va of I.C.A.S is 1000 V and the W_OPEP is 158W.
      Here you can get some information about the YL1070 heater characteristics.The heater voltage (Vf) is 6.3V (Pin:5-(1+7)) and 12.6V (Pin:1-7).The heater current (If) is 1.8A (Pin:5-(1+7)) and 0.9A (Pin:1-7).
      Then is about the capacitances(each section) of YL1070.The Ca (anode to all other elements except grid No.1) is 3.15 pF.The Cg1 (Grid No.1 to all other elements except anode) is 10.6 pF.The Cag1 (anode to grid No.1) is lower than 0.09 pF.
      The following is about the typical characteristics(each section) of YL1070.The Va (anode voltage) is 600 V.The Vg2 (Grid No.2 voltage) is 250V.The Ia (Anode current) is 40 mA.The g2g1 (amplification factor of grid No.2 with respect to grid No.1) is 7.The maximum temperature of bulb and all seals is 250.
      The last one is about the limiting values (each section) of YL1070 R.F.Class telegraphy and F.M telephony.The frequency (f) of C.C.S can be up to 60 Mc/s and of I.C.A.S can be up to 175 Mc/s.The maximum anode voltage (Va) of C.C.S is 850 V and of I.C.A.S  is 750 V.The maximum anode input power (Wia) of of C.C.S is 90W and of I.C.A.S is 75W.The maximum anode dissipation (Wa) of C.C.S and I.C.A.S are both 30W.The maximum anode current (Ia) of of C.C.S and I.C.A.S are both 90W. The maximum Grid No.2 voltage (Vg2) of C.C.S and I.C.A.S are both 300V.The  maximum Grid No.2 dissipation (Wg2) are both 7W.The maximum negative grid No.1 voltage (-Vg1) of  C.C.S and I.C.A.S are both 175V.The maximum Grid No.1 current (Ig1) of C.C.S and I.C.A.S are both 5mA.The maximum cathode to heater voltage (Vkf) of C.C.S and I.C.A.S are both 100V.
