The only place where it's critical to use non-inductive
power resistors is in the yoke return lines (where the
yoke connects to ground). An normal wirewound
resistor there will cause the output stages to oscillate
and make little waves appear in the lines.
In the high-voltage supply wirewounds aren't a problem.
Usually the electrolytics right at the power inputs (through
resistors) either open or short. A short burns up the
resistor, an open will cause noise in the picture.
His problem is probably because he substituted higher
value resistors. This not only increases the power
dumped into the resistors (meaning they run extra
hot), but can cause regulation problems.
