Now to order four 1000 uf @ 35 v caps and replace.

Thanks gents!!!
Yikes! I'd better check mine too. Is that goo from really from the caps or just glue to hold them in place ? I've never seen caps leak that much. Usually the tops bulge and start to crack along the "X"

Hard wiring the modulators to my sets cured the symptom entirely and gave me a much cleaner signal in the end.
Sure, but why use a huge modulator with a RF amp for one set ? You could get a much small, less expensive modulator for direct drive.
