You can use pretty much anything in an audio amp. How it will sound is a completely different matter.
To get low distortion you need decent linearity and a lot of tubes just don't have that with acceptable bias on their curves.
Personally, I like the Russian sub-miniature tubes - these are small, low voltage, wire ended, have great characteristics, are military stock so well made etc.
Just bought a bunch of 6P30B-R ( 6П30Б-P ) pentodes - 5.5W max plate. Very nice tube. Under USD 2 each....
Small is beautiful for me in the valve amp world...
