    Fender 5F11 trem circuit

    Can someone help explain how the 5F11 tremolo circuit works? I see it involves half of the first 12AX7 and the bias voltage gets to the 6V6s via the depth control, but I don't fully understand how it oscillates.

    It's weird, because it WAS working fine.....

    I started to write an explanation but Aiken does it better
    Experience is something you get, just after you really needed it.

      It is a low frequency phase shift oscillator.

      The trick is the caps that feed back into the grid.
      Over & over again.

      Lots of good explanations here:
