It's a fine tube, made my Marshall DSl 15 C red channel usable and the green channel still has the gain factor it was designed to have. I recommend this tube.

Bought this tube on a recommendation from a colleague. It drastically dropped the gain factor on my Marshall DSL40C without reducing gain on the 'green' channel. It dramatically smoothed out the 'red' channel and allowed more saturation without getting muddy. Best ever DSL40C upgrade...
