6SN7 tube question


Hello,

I need to replace the tubes in my Rogue 99 line preamp, which uses the 6SN7 tube. I was looking at an online seller who offers the following options with an affordably priced 6SN7 for a few dollars extra:

1. Balanced Triodes
2. High Gain
3. Low Noise and Microphonics
4. Matching

Options 3 and 4 seem most desirable for a preamp. My question is whether it is worth the extra few dollars (approx. $6 per tube) or is it just a pure marketing ploy to get suckers like me to drop more dough?

FWIW we find the Tung-Sol tube to be just as unreliable as the EH tube. Both are made in the same plant and the big difference is the color of the base.
There are three kinds of 6SN7s: GTs, GTAs and GTBs. If the circuit needs one of the latter two and you have been installing GTs, they won't last very long. GTs don't handle as much voltage.

We've been recommending Andy for decades- he is an excellent source.
