Telefunken 6211
The Telefunken 6211 is a high-gain, computer-grade dual triode tube , structurally and electrically similar to the ECC802S, but with a higher amplification factor (gain). It has a different construction than the ECC82/12AU7, featuring a higher transconductance and gain, making it a potential replacement where more amplification is needed, though it may have more distortion at higher voltages due to its design for switching applications.
