This is going to be a little more difficult than I had hoped for. The candohm resistor is bad and it is buried under other components...of course. It is #39 and 40 (8.5K and 25k ohms) on the schematic.

So my thinking is that a couple of 5 watt resistors should do the job of replacement. Here's my thinking (Mike, counting on you or Terry to correct me on this).

So the max voltage across that should be 240v which gives a max current of about 700 milliamps. That yields about .4 watts for the 8500 ohm resistor and 1.2 watts for the 25k resistor. I'll probably use two parallel 18k 2 watt metal oxide resistors for the 8500 replacement and a 5 watt 25k for the other. Sound about right?
