Actually, Chinese tubes tend to be very quiet in a phono section, but their life expectancy is pretty short. But for the price, you could pick up 10 or more for the price of a good pair of NOS tubes.
In my experience, I have also found that Chinese tubes don't have the "air" and openness or the high-end extension of NOS tubes.
