19) Because screen burn and swapped tubes, rotated yokes and reverse-connected yoke pins on Gleed's and Young's monitor recordings (which are probably not even Sanyo tubes any more) both create an image that is different than the true, legit and fully original cab that Billy Mitchell played on, set his records on and captured from.
I for one can attest I have gone to great pains to ensure the originality of the 20EZ in my cab. I bought it from a trusted seller in Los Angeles, replacing the heavily burned-in DJR Sanyo 20EZ monitor that was in the cab when I bought it, for the current TKG Sanyo 20EZ that is in the cab (bought from the trusted seller). Not to say that somewhere along the lines my monitor couldn't have been modified in some way, but parts are identical between the DJR, the TKG, the TKG in my red cab, other Sanyo 20EZ's I've worked on, etc, etc, etc. None of this truly has any bearing on the discussion, just some supplementary information.
