6DL5
6DL5 is also designated EL95. Completed sales put the typical price at $23.54 per tube.
Description
The 6DL5 is a vacuum tube for which the datasheet provides operating conditions as a class A sound output tube and as a class A push-pull sound output tube (using two tubes).
Single-Tube Class A Operation
As a class A sound output tube, the 6DL5 is characterized at plate voltages of 200 V and 250 V. At 200 V plate voltage, the plate current is 23 mA, the grid No. 2 current is 4.2 mA, the load resistance is 8000 ohms, the input A.F. voltage is 4.5 V (rms), and the power output is 2.3 watts. At 250 V plate voltage, the plate current is 24 mA, the grid No. 2 current is 4.5 mA, the load resistance is 10000 ohms, the input A.F. voltage is 5 V (rms), and the power output is 3.0 watts. Total harmonic distortion is 12% at both plate voltages. For an output of 50 milliwatts, the required input A.F. voltage is 0.55 V (rms) at 200 V plate voltage and 0.50 V (rms) at 250 V plate voltage.
Push-Pull Class A Operation
For class A push-pull operation with two tubes, the datasheet lists conditions at a plate voltage of 200 V and at several conditions at 250 V plate voltage. At 200 V, the plate current is 2×17.5 mA and the grid No. 2 current is 2×3.2 mA. At 250 V, the plate current is 2×20 mA with grid No. 2 current of 2×5.2 mA; a second condition gives 2×22 mA plate current and 2×4.0 mA grid No. 2 current; a third condition gives 2×26 mA plate current and 2×7.5 mA grid No. 2 current.
