What does the "high gain" option refer to when buying preamp tubes


I received an email from tube depot and I was browsing 6SN7s and noted that one of the options available was "high gain."

Does this mean that selecting that option for a tube would increase gain, or does it mean that selecting that option would be a better tube for preamps/systems that are already high gain?

Or am I cold on both guesses?

Thanks in advance/Matt

@yogiboy  , thank you.

But in that case do you know what Tube Depot is referring to with that option that they want $2 extra a tube for?

 

@designsfx  , thank you again, and with that explanation in mind, I emailed tubedepot with the exact same question, which is something I could have just as easily done before, but didn't think of it.  Part of the aging process I guess.

@designsfx  , thank you!  Since I feel I have too much gain, the "high gain" option would probably be what I would be looking for.  Thanks again.

@yogiboy  , thank you.  Just before you responded I did send them an email.  If they do not respond tomorrow early enough, I will call them before their sale ends.

Just to follow up on this, I emailed tubedepot and asked them what they meant.  The responded:

The "high gain" option is an additional test that ensures you received the tube with the highest gain that we have available, meaning less early breakup. 

And I emailed them back to say that I really did not understand what they meant,  and to clarify my question as to whether it added or reduced gain, and their replie was::

it only refers to the amount of gain a tube can handle
