Hi RATs!
I did not say tubes were not purposely designed. I said using tubes
for audio that were not designed for audio is neither sinful nor
foolish.
Not quite. You said "The reason a tube sounds good is the circuit it
is in, if it ever sounds good. Not because it was "designed" for low
(audio) frequency...

It most certainly does "matter what the tube was designed to do." A
remote cutoff pentode, for example, is a lousy choice for 'hi-fi'
because it was specifically "designed" for a different purpose and, as
a result, isn't very linear.
Still anyone who has listened to an AM, FM, or even an FM stereo
broadcast in the early years has listened to audio processed through
remote cut off tubes, specifically chosen because of their particular
nonlinearity.
Now, what's true is that some purposes share similar needs or may, at
least, be non conflicting. One would, for example, probably like a non
distorted TV picture and, so, use reasonably linear sweep tubes that
might also be suitable for audio.
At least in the Horizontal Sweep I didn't think the linearity of the
tube entered into the linearity of the Sweep? My gut feel may be wrong
on this, it's an interesting question, I will have to study up on it.
