Thanks Siggi. I found that article and it inspired me to dig into my repair. Since Mark used an 0603 SMD resistor I assume the power requirement is pretty low but i thought i'd ask others. I can probably squeeze a 1206 in there, but it would be much easier scrape away the remains of the old resistor and solder in a 1/4 watt resistor (or two in series). I was mostly concerned about the power rating of the original part, but given the size, I guess it's pretty low. I'll try the metal film resistors, matched to the value of the resistor in CH2 and see what happens. Hopefully nothing on the underside of the board is also blown. I'll post my results . . .
