Just to clarify: 833's have two filaments in "parallel", one can break
and the other can survive on rare conditions. Just break one apart and
see. ;-)

David -

In a recent post, you mentioned: "Also I had two
833A's with only one functioning filament each....".

Are you confusing an 833A with the 304TL/TH series of triodes?

All 833'a have only a single filament; when it's broken or burned out,
its
all over. All 304's have dual filaments and will still provide reduced
output when run on a single filament.
