[Amps] 500 volt Electerolytics

[Gary Smith]

I'm picking up an amp this weekend and would like to beef up the 
power supply. It uses eight of the shorter screw type electrolytics 
and rather than use 450 volt, I want to replace them with 500 volt 
versions. Cornell makes some and perhaps other manufacturers do but 
they are pricey in small numbers even from Mouser.

Anyone have a suggestion where I might better look? 

I will be at Dayton but would like to get them sooner if possible.

Thanks,

Gary
