Apple III Power Supply: Success (I think...)

So...  how do I tell whether the capacitors I've put in there are low or 
high ESR?  Are there particular markings I should be watching out for?  
I just bought these from the local electronics shop, I had no idea there 
was anything to look out for aside from voltage & capacitance.  Guess I 
shouldn't assume these things :).

Thanks,
Josh
