NOS 12AT7 at "first 2 position (Cascode?)" in MP3?

I have been using all 7 Chinese 12AT7s in phono stage for the past 8 years, without hums or noise.

Recently,I have been mostly using line stage only from server, with the 4 posterior 12AT7s removed.

I am wondering if the first 2 position 12AT7s and last 4 posterior 12AT7s have the same amplification requirement?

I have quite a few NOS tubes in hand. They have worked really well in my other equipments.

Would NOS 12at7 tubes (cv4024 6201) be OK in the Cascode position, with Chinese tubes in the last 4 phono positions?

Thanks for your input.
