Obviously bad connections, easily reflowed and cleaned up. Could very well be your problem. You will know soon enough.
I usually find the 125v B+ in the flat pan chassis such as your 25EC to be 120-130 depending on the line voltage. IIRC this supply is regulated by the resonant circuit formed by the power transfomer and the 3.3uf oil capacitor. There is no regulator that you can adjust. The 24v supply does have a regulator, set by the zener diode in the base circuit. If your jail bars are vertical, as they typically are, the "ripple" is at a horiz rate leaking into the video, more likely the boost source. Are you looking at Sams? Which one? or the Zenith CM?
