I can confirm that the tube is a direct transplant however I do not know about the HV board. I used a 5110 to replace in the tube in one of my 577's no modification needed.

It has a crisp stable display. Looking inside, I see that the display half is nearly literally the top half of the 577 D2, just as Andy mentioned. The only differences I see are the calibrator loop and that the connections to the HV board are directly wired instead of pin connectors (cost savings, I guess). Given the soot that was all over my HV board, I'm inclined to perhaps just transplant the tube and the board. The schematics seem identical, unless I'm missing something I'd only have to convert the cables to connector pins. Has anyone tried that as well?
