High-vacuum electron tube with thermionic cathode and control grid for demonstrating the thermoelectric effect (Edison effect).
Use the tube to investigate the practical applications of a triode as an amplifier and generating undamped oscillations in LC circuits. Also investigate the characteristics of triodes and let students discover the negative electron charge polarity. Specifications Max. heater voltage: 7.5 V AC/DC Max. anode voltage: 500 V Anode current: approx. 2 mA at 200 V (Anode)
