If you're good at soldering it's no problem to switch caps. But that's a
common advice online and hence the scepticism. Michael knows what he's
talking about and you seems to know how to solder. But there are plenty
of stories from hobbyists digging into old gear causing soldering
bridges and other things making matters worse.
So my comment was not negative, just an advice to take it slow. But if
Michael adviced you to do it, it's a different matter. :D
