for this thread, can we all just at least argue for convenience sake that all variations of rectifiers (notwithstanding chronological versions, ie pre 500, etc.) sound pretty much almost the same. especially the dual and triple and the offsets like roadkings and roadsters.
there is oh such a small difference that you would have the same thing in two same consecutive serial dual rectos. this doesn't include things like saturation points and headroom because clearly a triple rectifier has more headroom and overall juice than a dual or single, but at the core they have the same heart and distortion sound so their variances tone wise especially in a controlled environment like a recording studio they get very very very close to each other.
