Elekit tu-879s Higher than normal voltage

I have assembled yet another one of these great amps,however the voltages are running a little high.I am wondering if I have the wrong R-core transformer for 120v ac input.I measured the output of the transformer at 296 volts ac.I also measured capacitors 15 & 14 to be at 442 volts.Is this too much voltage for those 400v rated caps? There isn't anything indicating the voltage rating on the R-core transformer-other than PT-877 KIG1SK
