My question: was the 2 watt power rating for withstanding voltage vs power dissipation? If so than a single 39M 1 watt HV resistor would make for a simple replacement: https://www.digikey.com/en/products/...5JAC00/9693129 they even make a 36M value but are not in stock nor sold per each.

this probably has something to do with High Voltage Creepage and the fact that resistors back when the set was made had a less potential to handle high voltages like the ones made today. IE one can do today where 2 or 3 was needed 50 years ago.
