- Lots of information around concerning the real need to HI-Pot / Getter glass tubes - especially concerning the popular 3-500 series. But not so much concerning the same need for Ceramic / External An

- You can't run the finned plate of an air cooled plate orange or red, so the MFGs spot weld gettering washers and disks to the leads between the base and under side the elements. (operating the plate

- Interesting question... many external anode tubes are "self gettering" in-so-much-as the gettering substance is painted on to the cathode and the process of running the tube (heater on) is sufficient

- ... and the thermal "mass" of an external anode tube is huge compared with the relatively small internal anode on something like a 572B or a 3-500Z... hence which the same amount of kinetic energy ma

- It is much more complicated than thermal mass. Thermal mass only determines how quickly an object will change temperature for a given amount of heat flow not how hot it will ultimately get. Radiation
