|I used a Tektronix 475 in the below video. Not sure what the difference between the 475 and 475A is though.
TBH, for vector rescanning, I'd go with a Tektronix 608, 620, Leader LBO-51MA, or any other X-Y vector display over an oscilliscope with Z input. Many scopes, including the 475 don't have a removeable graticule and I find that the lines are a lot finer and more accurate on the XY displays. Unless you're cool with the graticule and smudgey, thicker lines.
