Hi Richard,
The current through the display is limited by the resistors R7, R8, R17, R18. These resistors need to be able to handle some heat. They should be rated at least with 2W, better 5W. Please have a look to the photo below - the big light green Resistors are 5W-Pieces:

The 33k resistor (R2) needs to be rated 1W. I have here two 0.6W resistors in parallel.
