I'm working on the PS of my gainclone and have a couple of CHIA YU LU (sp?) trafos that I'm running through MUR860 diode bridges. When I hooked it up and powered it, I read ~+-22Vdc. A few days later after putting snubber caps (.022mfd, 200V) across each diode, it now reads ~+-26Vdc. I'm no EE, so could someone please clue me in on what might have happened? Can caps raise the output voltage? If so, it's certainly news to me. BTW, I smelled and heard nothing indicating any problems and the voltages were steady across all four output voltages.
thanks

I made the same measurement before without snubber caps and without load and got +-22Vdc. I have another set of trafos that measure +-18Vdc at the bridge without load, which is its rated voltage. So two out of three measurements saw no significant increase over rating without load. What would be different here?
