6SL7

Posted by drlowmu on March 20, 2017 at 00:20:05:
Even better to drive the 2A3 in a direct couple with a mu of 100 Tube. A 6SL7, (a) besides not having the higher mu, has (b) an inherent degrade in the solder connections of all the leads, going into the Octal socket's eight pins.

Nice to avoid (a) and (b) by using other NON-octal based tubes.

Listening-wise, the mu of 70 6SL7 won't be quite as much fun to hear, as it will fail to have the subjective positive qualities of a mu of 100 driver, particularly at low to medium listening volumes.

None of the available driver tube choices are perfect, but the 6SL7 is less perfect, more compromised from the start, than other tubes one can choose.
