Hi,

I have several CV5843 Twin triodes, do they have a civilian equivalent
and are they any use for audio? Google shows many of the part finders
offering to sell me them but little else.

Google shows " 5965 " as another name for the CV5843
now Google for " 5965 triode " and you will find.

You need

Get to the "Tube data sheet locator" and it will lead you to
the "close or identical" 5965A, for which there is a little
data. If you follow the lead to the "different ratings or
performance" CK5965, you will find a datasheet with anode
characteristic curves.

Differences are likely to be such details as heater voltage,
base and pinout, so you need to be cautious. Characteristics
of operation are likely to be the same.

Looks OK to me, but it's not a direct replacement for any
common audio valve AFAIK, so you'd have to design a circuit
for it. Why you might want to do that I don't know.

It's designed to spend most of its time in cutoff, with
occasional zero-bias pulses, so there may be a question
about its longevity in an audio application, where it will
always be passing current.
