RE: Are tubes better at voltage gain or as amplifiers

Posted by Eli Duttman on May 4, 2017 at 08:08:12:
As Tre' indicated, tubes are voltage controlled and BJTs are current controlled. Like tubes, FETs are voltage controlled, which makes them fairly easy to combine with tubes.

In hybrid circuitry, tubes for voltage amplification and FETs for current amplification is a reasonable "mantra". Dig into the archives for the tweaked RCA phono preamp, for an example.
