Post Subject: not parallel SETPosted by morricab on: 6/27/2007
Hi Romy,
The Vacuumstate amplifier is not a parallel SET it is basically like push pull but with some kind of trick dynamic bias control that keeps the tubes really together. Much of the low level information that gets lost with the usual push pull is lost in this transition between tubes mainly because the tubes biases are changing and they no longer match up properly. Vacuumstate has figured out how to keep them extremely close together so that they retain the strengths of SET in a "differential" design. You can read about it on their website http://www.vacuumstate.com/
