Replacing stocks caps with lower voltage ones is a dangerous thing to do unless you are absolutely sure of the wost case scenario.
The Supplyvoltage from the floppy-connector is +5 and +12V, but what comes across the cap.. I have no idea, but since they're 10V caps (right?) it's should not be 12V? I was not planning on putting it in without knowing for sure. But I figured I'd ask here if you or somebody else had measured. It's common sense not to put a 6.3V cap where a 10V is placed without being sure if it'll go poof or not. (for most people)
Normally I'd just grab a 16-25V cap and be done with it, but I got a pair of decent caps for free from a friend yesterday. So that's kind of why I wanted to check before buying something I wouldn't need. I have a multimeter but there is no chance in hell i can reach any measuring points in the cramped case. I'll figure something out and get back to you guys.
