It a amazing tube in my Manley Chinook amp - Top notch :-)

Best 6922 I’ve used

by -

Best tube I’ve used in my conrad johnson preamp. Crystal clear from the top to the bottom of the frequency response. Tight bass. Excellent space between instruments. Vocals are right on. My preamp usually eats tubes, but the SQ has lasted for well over a year so far with no deterioration or hiss.
