Beschreibung

The M4205 tube is similar to the 4205E but has the grid and anode specially treated to reduce secondary emission. It was first made with a nickel plated base but this was later changed to Bakelite. Under safe operating conditions, the maximum anode voltage is 400 and anode dissipation 15 watts.
