This readily available dual triode has electrical properties very close to
ECC32/CV181
and yet it appears to be totally neglected in the audio world.. Could this
be because of its
uncommon base (B8A) or the fact that there is no US equivalent driving US
designs
or simply because it is not a good audio tube... Any input appreciated.

The ECC40 is an exellent audio tube. It was widely used in studio
equipment - mostly German production e.g. Maihak, Telefunken ...
