Reporting question for Vacuum Tube - 12AU7, China

Vacuum Tube - 12AU7, China

I can’t find any information about this tube on Can you compare this tube with Chinese 12AX7B with parameters like noise, low, mids and high? Will this tube reduce Lows and Gain as well as maybe some noise ? Im planning to put this tube in socket V1 instead of Sovtek 12AX7WB

This will reduce the gain and even possibly the volume output of the amp, but it will have a comparable noise floor.
