    Good preamp tubes but true NOS are hard to find

    12B4A is a good choice for preamp because of its low amplification factor. However true NOS are very rare. I tested a total of nine from three sellers using Hickok 752 tube tester, Tektronix 576 curve trace and Tektronix DA4084 Programmable Distortion Analyzer. I only got 3 decent 12B4A's out of a total of 9.
