SUMMARY
To supply power to a Mullard vacuum tube, specifically the EL-34 pentode, one must generate an electron beam by applying the correct voltage and current. The maximum plate current for the EL-34 is 100 mA with a maximum plate voltage of 250 V. Proper biasing is essential, as the difference between the maximum supply voltage and the anode voltage accounts for the cathode bias resistor IR drop. Refer to the Mullard datasheet for detailed specifications and guidelines.
