TESTED TUBE 6211 AMPEREX NOS NIB
A less common vacuum tube, this is a class A amplifier twin triode with
medium mu; lower gain than the typical 12AT7, even lower than even the
5965. It usually has larger, flat plates with diamond shaped
points at the corners bent inwards. This construction adds rigidity to
the plate structure. This vacuum tube is slightly lower in plate voltage
and current ratings, but is still very usable in hi-fi stereos.Often
used in preamp circuits with lower gain, lower microphonics, and mellow
sound. Somewhat uncommon but this medium-mu tube sounds very good in
place of the standard 12AT7. Great for making the gain on a guitar amp
more usable or eliminating harshness in your stereo system.
