About Diode (NOT rectifier) tubes
This type qualifies if the tube is described as a signal diode, or other low power diode, NOT a rectifier. Also if multi sections of all diodes, go to this tube type. And there are no other sections that take priority in assigning the type. Signal diodes get lowest priority across tube type assignment. If the diode accompanies another section... if the accompanying section is a triode, evaluate the various Triode type assignments. If it has a pentode or tetrode then evaluate the tube type assignment by those types. If the other section is a beam power then evaluate that as highest priority assignment evaluation.
