The question is, would it drive the 19" tube that's in there, as there can't be that much difference?
Highly unlikely, as the scanning power required for the wider neck 19" CRT would be a good deal more and the DR101's scan coils are for a 28mm neck, whereas the Bush Ranger is a much smaller CRT neck diameter. Then there's the question of higher peak-to-peak video drive to the 19" CRT's cathode and the 19" CRT's A1 and focus electrode voltage requirements would be higher.
