Bulging Capacitors

70.71.27.156

I have a Moth 2a3 tube amp. After taking the top cover off to tighten a RCA plug that came loose, I notice the tops of 4 out of 5 power supply capacitors were bulging/ballooned out. Should I have any concerns on this? What would cause this. The amp is working 100% fine.
The cap. values are 220uF/450V. If I do change them out, should I change for higher value say 330uF/450V? Will it make any audible improvements?
