Kenwood Chef A701/A702 v A703C resistor value?

What is the difference if any, between the models. I have an A703C
with blown cap's and resistor, the resistor value is unreadable and the only info I can find is on the 701/2's and 900's, the cap values are all the same 0.15 and 0.047 so am I right in thinking the resistor is the same (56 ohm) I found a post recommending 2 watt but the original appears to be 1/2 watt.
