Just a Note on Using LN-317 as a CCS

Walt Jung published an article in AudioXpress on Current Sources. One of the circuits was a cascode based on the LM-317. Dave Davenport of Raleigh Audio implemented it in his Line Stage kit as a plate load. At the time I had one of his Line Stages and I tried it. It caused a noticeable amount of White Noise. This was due to the LM-317. I don't know how much this would effect its use as a tail impedance; but, as a plate load, unacceptable.
