Well you cannot run the plate current through the voice coils, so you still need a large hunk of iron as a plate choke and a coupling capacitor. You could use a resistor instead of a plate choke and throw away efficiency and tonal magic. The array has potential if you can get around inherent lobing issues.
Why not? What if a transconductance amp is used, with the output tubes serving as current sinks, with speakers between their plates and the regulated B+?Originally posted by rcavictim
