Grid Stopper Resistors.

Posted by sony6060 on January 7, 2017 at 11:42:35:
Ultra high gain tubes need grid stopper resistors. Typical value is 1K carbon comp resistors.

What about low gain such as a 6SN7 tube & would a grid stopper alter the sound? Or 6V6GT power tubes in tetrode or triode connection. Tetrode has about 6db negative feedback, triode no feedback.
