Dave,
I would also place suitably rated, beefy MOVs across the input and
output leads of the bridge, and possibly across each individual leg of
the bridge. Rearranging the wiring have caused the system to pick up RF
in a new way that is blowing the bridge.
I'd also place suitably rated 0.1 uF ceramic disc caps across each leg
of the bridge to bypass stray RF. Electrolytic caps are too slow to
protect against RF at TC frequencies.
You might try it without the line filter in the output of the bridge.
The LC combination in the filter may be causing resonant rise that is
toasting the bridge. Sometimes, filters cause more trouble than they fix.

Hey guys,
I'm in somewhat of a dilemma over a recent problem that has started plaguing me when I fire off my big SG coil (Green Monster).
