First I have to actually get it running again, I am not a tech, so my circuit board repair work is really ugly. Assuming I get that far ok, then I would be happy to take some measurements with my multimeter.
I might need some help where to poke the probes to get the input cap values mentioned above. Perhaps the photo of the new one showing most of the board will help with that. Why be so careful? what voltages are we looking at anyway--not just the 120v? If it is way more, I don't know how high the meter goes. The above quote must be AC 150v not DC?
The rectified voltage at the caps will be ~170vdc if properly filtered, so definitely be careful. You'd get a good tingle from a lot less than that! Most meters (even cheap ones) are good to at least 200vdc.
Please let us know what you find out when you have a chance. I'm always curious to find out what causes electronics to fail.
