A double triode can be used to make a 2 channel preamp.. Or the 2 triodes are used for 2 stages (one channel ofcourse)

Common use could be a lot of things depending on the type...What type do you have?

I think they put 2 triodes in one envelope to save space.
If you can see the speaker cone move...it's not hifi.

A common application for double triodes is as a differential amplifier such as the driver stage in a Williamson amp, or as a long tail pair phase splitter such as in Mullard, Leak etc. Two equally specified triodes in one envelope tend to be better matched than two completely separate tubes. There are a few types, though, where the two triodes are deliberately not equally specified and are meant to serve different purposes. Putting two triodes in one envelope saves not only space but also cost, which is important for manufacturers.
