Rolling tube 6dz4 to 6af4 caused problem in 10B

88.209.233.112

I'm a regular tube roller to hit better sound.

The 6DZ4 was sucessfully replaced by 8334, without any problem.

But replacing the 6DZ4 to 6AF4, beside the target station a neighboring station is also sounded quietly. I can't posit the dial button to avoid this situation.

This is true for both RCA and TungSol 6AF4-s.
The 6AF4 higher resolution and dynamic than the 6DZ4/8334, so I would like to keep the 6AF4 if it's possible without hearing neighboring radio stations.

Any idea ?
