Is it possible to adjust bias on each section of a tube ?

[ Follow Ups ] [ Post Followup ] [ Thread: Display All Email ] [ OTL Asylum ]

This would be great, but I suspect it might be quite difficult and expensive to do, but in my simplistic view, couldn't someone buy 32 cheap, small, plastic body pots, and wire them in to each section of a tube, off a pin, and have the ability to adjust the bias of each section of every tube?

no because as i understand it the output tubes grids are driven by
a direct coupled cathode follower. You would need 16 cathode followers
instead of 2.

  In addition to the 16 pots and the 16 CF, you would also need 16 coupling caps instead of 2. It gets really messy.
  Lew is running 6 caps/pots/CF to separately bias up his 6ea 6C33 tubes in each of his amps. Contact him to learn more.

    or you could use 16 pots and 16 caps with the two cf's you have.
    The bias supply would not be part of the CF. With this arrangement you would only be adding one cap per phase. that's the down side. the up side is all the triodes would be running at the at the same idle current.

      Tre,
      
      You lost me. Can you describe the arrangement and how it works?
      Thanks, Paul
