Strange voltages on speedball boards after installing film capacitors

Everything on the amp was working great until I replaced the 100uf electrolytic caps with two 250v 100uf Erse Pulse X film caps. When I did a voltage check on the Speedball boards I got the following voltages. While I was installing it one of the speedball wires did break but I replaced it. Do these voltages mean I wired something wrong or is there something special I'm supposed to do to use film caps? Any help would be great! The voltages are below.

Small Speedball board...
0A:178.3V
1A:185.9V
A/B:113.5V
1B:185.5V
0B:177.7V

The correct voltages would be...
0A:60-90V
1A:170-270V
A/B:0V
1B:170-270V
0B:60-90V



Large Speedball board...
0A:177.5V
0B:177.3V
G:112.1V
B+:185.7V

The correct voltages would be..
0A:75-100V
0B:75-100V
G:0V
B+:170-195V
 
Voltages will not change when you change the output caps. Ergo, you have a bad connection somewhere. You may have missed another broken connection.
