errr...not being critical( too much...LOL), just trying to take exception of the simplistic FB statement made by chip.
I built an open loop amp around the Dyna A441 outputs once. Sounded pretty good with the tertiary winding feeding the screens. Sounded even better with a fixed g2 voltage and the cathodes riding the screens. On a wide variety of speakers the CFB rigging was The Way To Go, but on a few, open loop U-L was a little bit better.
Then I hit upon the Plate-to-Grid implementation we called E-Linear. Not looked back, and built several full pentode amps of that topology.
cheers,
Douglas
