Is there any chance one of the replacement electrolytics could've got installed backwards?
I been looking at the schematic posted by Vts1134 in another thread in another forum. Is this the same schematic you're using? If so, it incorrectly shows C220C with its negative side to ground and its positive side to the negative 100V supply rail. I.e., it's shown backward.
If connected as shown in the schematic, it would definitely be a problem.
