Keith,
For the two 39meg resistors (R710 and R910 on page <5>), two of 594-VR37000002005FA1 in series will work. For the 100 meg (R1991 on page <8>), 708-HVA12FA100M or 588-SM104031006FE (check length of pins of original and this on to make sure it will drop in without bending the leads. I looked under 'ohmite resistor' then 'thick film resistor'). The part numbers are Mouser. If you have any more questions, I will be glad to help. If you chose to raise the NTV value to 10/16 ohms, a 527-CL60/70 will work in place of RT1010 off the mains.
Depending upon the amount of dust inside, removing the crt then cleaning it and the shield may be best. Removing the dust prevents a leakage path due to dust and moisture on the dust. Clean the filters also while the crt is out. That will make the trace clearer and sharper due to dirt being removed.
