Heat Vacuum Tubes Temperature at Latanya Gail blog

Heat Vacuum Tubes Temperature. Of about 290° c and the wall of the experimental tube experiences a maximum temperature of only about 80° c. In a hard vacuum, heat cannot be conducted from the plate/filament to the glass, but it can be radiated. Lowering the heater voltage, and thus, the cathode temperature too much will shift the tube’s characteristic down to a lower saturation current and increase distortion. The dc power input for the nichrome. On the other hand, the heat is. Tubes are supposed to get hot and their glass enclosure can reach upwards of 300 degrees fahrenheit under normal circumstances. To prevent overheating you have to make sure that the amplifier has sufficient ventilation to keep it from baking and that it is biased correctly for its power tubes. Both the 12ax7 (ecc83) and ecc85 heaters are designed to run on 6.3v, but the ecc85 heaters draw more current because they have to. The basic working principle of a vacuum tube is a phenomenon called thermionic emission. That may not be a problem with low power (pre)amp tubes, but it might be an issue with power tubes.
