You don't want to replace the two 50uF's with a single 100uF. They and the 1K resistor (plus transformer inductance) make up a PI filter ( https://circuitdigest.com/tutorial/pi-fi...esign-tips, https://electronicscoach.com/pi-filter.html).
As far as the values new capacitors you get probably have a 20% tolerance (50uF => 40uF-60uF). I have to think the originals weren't any better...
Can't think of anything witty.
