Because the heavy electron current in such tubes damaged the dynode surface rapidly, their lifetime tended to be very short compared to conventional tubes.
One difference between magnetic logic and conventional tube or transistor systems is that it is the current that defines the logic levels, not voltage.
RCA's solution was to use three conventional black and white tubes with filters on the front to produce the three primary colors.
Where a single brief event is monitored by an oscilloscope, such an event will be displayed by a conventional tube only while it actually occurs.
To use smaller tubes instead of conventional sized tubes in air conditioners, heat exchangers must be redesigned.
This allowed the tubes to be built with much higher deflection angles than conventional tubes - 72 degrees as opposed to a more typical 45.
Playing the radio with conventional tubes for extended periods occasionally drained the battery to the extent that it could not start the car.
Most nuvistors are basically thimble-shaped, but somewhat smaller than a thimble, and much smaller than conventional tubes of the day.
An additional drawback of the conventional 19 tube, tube bundle is variation in sizing.
