If supply voltage is higher than normal you may have some shorted turns on the filter choke. If supply voltage is lower than normal you may have reduced value of filter capacitor. If ripple frequency is 120 Hz it is probably NOT a bad diode in a bridge. If ripple frequency is 60 Hz it is probably a bad diode in a bridge. - Jim W4ENE _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
