GenRad 1381 solid state random (white) noise generator. A few paint scratches, but works perfectly. Adjustable bandwidth in 3 steps: 2Hz - 2kHz, 2Hz - 5kHz and 2Hz - 50kHz. I have another one of these that I use to plot frequency response in transformers, preamps, compressors, etc. The industry has long used white noise to plot mic frequency response as well. A useful tool for the testing bag.

In my measurements, actual bandwidth is closer to flat from 2Hz - 60kHz.

$65 plus shipping.

I'll also be posting some more test gear, including a tube tester, a nice Leader Function  Generator and a few other items.
