Like Peter, I would suspect one of the diode stacks has gone open circuit. If it was the filter capacitors, the hum would be 120Hz. If it was the cat, the hum caused by purring is modulated at a lower frequency! 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
