Swapping old capacitors for modern caps
Assuming the actual value of the capacitors is 2200uF, any modern electrolytic of the same physical size and value from a reputable company should work. Make sure it's rated for at least 63V, more is ok. Slightly higher capacitance may be ok, but we would need to see the circuit diagram to confirm this. Try to find caps from Panasonic, EPCOS, Nichicon, Rubycon, or Nippon-Chemicon. They are some of the most reputable capacitor manufacturers out there.
