Eneroid Electron tube, EM80 or equivalent 6E1P

The EM80 electron tube, also known as 6E1P, is a special indicator tube commonly used in radio technology. It is often referred to as a "magic eye" and serves to display signal strengths in radios and other electronic devices. This tube is known for its distinctive properties that allow for precise display of electrical signals. The EM80 is a diode-type tube capable of handling both forward and reverse voltages of up to 250 volts. Its applications are primarily found in radio repair and the development of vintage audio devices, where it plays an important role in monitoring and optimizing signal quality.

• Maximum forward current of 3 mA
• Characteristic forward voltage of 250 V
