EMISSION LAB 20B
This is a medium gain, medium impedance tube. It has a very pleasant triode sound, due to almost total absence of the third harmonics. At lower voltage around 250Volt, the characteristics resemble 6SN7 quite well. At medium voltage it is a wonderful driver tube. At higher voltage, 20B comes alive as a power tube, capable to deliver a few Watts.
