RE: Smoother tube than RCA 6080?

Posted by Tre' on April 7, 2023 at 12:24:32:
That is unthinkable to me. The 6080 is way different than the 6sn7. For one thing, the 6080 draws 2.5 amps of heater current, the 6sn7 draws .6 amps of heater current.

The 6080 has a plate resistance of 280 ohms, the 6sn7 has a plate resistance of 6700 ohms. The 6080 has a mu (gain) of 2, the 6sn7 has a mu of 20.

The one will not work properly in a circuit designed for the other.
