I do not believe, it is a design that stems from the original super group amps...which are all there own thing, but much as we all know....most of the stuff evolved from the bassman....but if you look at the history of Lyndon Laney he knows music and amp design...just look up the history, it is way cool.
As with all the loud amps from this period....aside from the daynakit based ones, they all had similarities and they all coped stuff from each other. From my understanding, vintage Laney magic is in the original transformers and speaker cabs.....
But, this has its new and better heart? Maybe.
I'm only offering a different option...and opinion.....so take it for what it's worth.
I may have schematics somewhere that show the original pre, because I wanted to build a pedal based on it.....one of many projects.
