Well, it sounds perfectly OK to me, but what do I know? What did make me
larf is the 'rosy glow' of the valve (visible through a little red window in
the front of the mic) is actually an orange LED set in the valve base! It
is, I've looked closely and seen it! You can see it here (scroll 2/3 down):

Why is it 'audio types' are so easy to bullshit?

X-Files 'I want to believe' thing?
