I would not go under capacitance on the caps...first thing I would do is make sure all capacitance values are at least as much as the originals. If there is a resistor that is off value I would just replace it.
Then I would try and see what portion of the set is accounting for the excess current draw: try removing branches off the power supply (remove the Horiz and vertical outputs so they don't get damaged by a lack of oscillator voltage) and see if the voltage returns to normal. IF not then check the no load power supply voltage...if that is still low the problem must be in the power supply and not the set circuitry.

What is the ac voltage at the power transfomer secondary? is it in spec?
Also is this a bridge rectifier or voltage doubler. if bridge you might see if one of the new diodes might be bad.
