It is generally considered not good practice to have the value of the output capacitors larger than the power supply reservoir capacitors. The original output capacitor is 1500uF and the reservoirs 4000uF.
So by putting in 4700uF's in the output stage, you'd need at least 10000uF or even 15000uF as the reservoirs. That would put a strain on the bridge rectifier which was not designed to feed into such large capacitances. It might even affect the mains transformer and the mains fuse.
If I were you I'd put in 2200uF's for the output stages and 4700uF or 5600uF or maybe 6800uF for the reservoirs.
