Well.... a lot of TC'ing is demonstrating craftsmanship and "cool looking"
stuff. (It's those "Fine Corinthian Leather" knobs on the variac, for
instance)...

There's a heck of a lot of stuff in TCs that isn't strictly needed for
performance, but is more because they're works of art.  There's something
satistfying in a wood cased grandfather clock with a pendulum going
tick-tock, even though an imported $10 Chinese quartz Timex knockoff is more
accurate.
