It looks like my dead-ish SVT was down to R59 in the power supply failing spectacularly. This is the resistor that feeds the 380V rail for the final stage on the main board that drives the output tubes. My immediate thought is to replace it with something that has twice the wattage rating, but before I did that I'd like to check the collective TB wisdom as my expertise is more in the 20nm sub-1-volt range than big hairy tube gear. First question: is the higher-wattage replacement a smart thing to do? I know that's generally regarded as a bad thing to do when replacing screen grid resistors but this looks like just a dropper resistor on a power rail. Second question: is this more likely to be "just one of those things" or a symptom of a problem somewhere else that is likely to come back to bite at an inconvenient time? Thanks in anticipation for the wisdom. edit: I just noticed - you can see it in the pic - that C22 has also failed.
