Yes. It seemed the obvious choice for the bus. An
alternative would be an ordinary gain stage with a low value
grid resistor.

I couldn't maintain interest in mixer design beyond getting
the ideas straight. It seemed like a fool's errand, and
still does. I can't see why a valve mixer is a good idea. A
box of mic amps, yes, with a state of the art SS mixer amp
and chip earphone amp, maybe.

And I could only copy a respected valve mic amp, considering
I've never done any recording and have no idea what they are
supposed to sound like.

And I noticed that no-one else has actually posted very
specific details. Coyness, in addition to the usual
animosities, was clearly going to frustrate any attempt at
serious discourse.

And I don't know enough about noise to adopt a rational
strategy, and this particular mixer idea isn't a good
learning vehicle because I don't care much for the money or
its man, for whom I suggest Eeyore is a good match, which
is what I said, and still think. The man doesn't want what
he's asked for, and Eeyore won't provide it.

John seems to be taking it seriously. Never seen him so
keen, bright-eyed and bushy-tailed, deserves a prize of some
sort.
