Default Damper diodes as rectifiers


They advised that damper diodes be used only for their intended
function for a reason.


Which could just be marketing.... But not likely, as no damper diode
ever had two separate plates like regular rectifier tubes had.

Operation at less than specified filament voltage, or asking them to
pass current before they are are fully warmed up, will cause shortened
life. And even if operated "properly", the only effect will be that
they have a sharper cutoff on the negative portion of the cycle, just
like a silicon diode. So if silicon diodes are bad, the damper diode
is too.


Other indirectly heated rectifier tubes, like the 6X4, would also have
that issue.
