Cheaper to replace em' than buying an ESR meter, at least this way you 'know' that they are new and not likely to give problems.
Whichever way you do it, always use high temperature 105 deg. C types (or higher) low ESR types, this is important.... use standard type capacitors and you'll soon be repairing it again, these are easily obtainable and not costly.
It's OK to up the voltage, say the caps are 1000uF 25V for example you can use 1000uF 35 Volts types..... take note of their sizes and pin spacing though. Components are usually packed like sardines making space very limited.
