Hi all. I have the typical random channel switching problem on my blues deluxe. I have opened her up and sure enough, the 470 ohm resistors at R85 and R86 have bad solder joints and show overheating on the PCB. I will replace them and raise them from the PCB to let them breathe. Would someone please tell me exactly what resistors to buy to replace these?

Schematic is here.
Should I clean up these solder points and test voltages on other components before replacing the resistors?
It may be worth noting that the problem occurs only when the clean channel is selected, and only when I crank her up. If I select the overdrive channel, the random switching does not (ever) happen.
Thanks!
