thanks Dave
No its easy enough , i discharged the CRT and took the board completely off. The heatsink has 2 cross head screws holding it down and one on the regulator too, unscrew them and pull the 2x tabs back and lift the regulator up straight.
The heatsink lift cleanly off. You can unsolder the reg from underneath easily. refitting is the reverse but i put a smidge of heatsink past on the reg before screwing it down.
i popped 2x clips for the voltmeter on the reg before powering up so i don't have to try and put probes inside there - far to easy the short something or get electrocuted.
easy job really.
