The schematic lists capacitors C34, C35, C36, C37 each at 1000 volt ceramic caps. Can these be substituted with caps rated at 500 volts, or should 1000 v. be used? I realize that cap voltages should not be decreased, but 500 volt caps were provided in the kit. Was the original 1000 volt value listed on the parts list "overkill"?
Thanks.
