The tubes see the speaker characteristics and vise versa, no transformer made can allow that to happen if it's in the signal path!Unfortunately, perhaps, his patent application for this idea describes it as having as an essential component, a transformer smack dab in the middle of the signal path between the output stage and the load (e.g. speaker).
No, not at all, this is not a accurate statement!
Yes it is a reasonably accurate statement, because another essential component of his idea, as described in the same patent (#5,612,646) are groups of power mosfets (also in the signal path), which are known in switching power supply and Class D amplifier circles as comprising an 'H Bridge' configuration. These power mosfets are switched between 'saturation' mode and cutoff, also typical of their application in switching power supplies and Class D amplifiers.
