Barry,
These are a bleeder for the cathode circuit and partial divider for high voltage and focus circuit. I replaced mine with 1W 1% types and spaced them off the board. The 1W types I use are about 1cm in length, not 3,68 x 8,74mm types.
You will find the two 22meg resistors to be well out of tolerance. Use VR37 Vishay types.
