I'm working on a Bogen CHB50 and the replacement filter capacitors are much smaller than the mounting ring hardware that held the originals. Should I try to resize the hardware (they're sort of like the ring that the lion tamer would have the big cat jump through, except these are riveted to the chassis)? Or would a blob of hi-temp silicone work? I know some of the silicones have acidic curing byproducts which wouldn't be good for the parts or solder or the chassis. Anyone ever go the goo blob route of mechanical attachment/isolation?
