Default Simple Test Circuit for Tube Noise

Use the right transformer, and it works fine. Try the Jensen JT-13k7;
the thermal noise only adds 1 dB, and the bandwidth is good. It's the
tube used in Dan Kennedy's original preamp design, which is very clean
and neutral. It turns out the same transformer does a fine job with a
vacuum tube.


That's about as good as you can get, yeah!
