Need Help. My fuse blew in amp. Changed worked fine then one day cut on heard loud buzz opened up inspected and had dc volts on output speaker +-7v got a schematic found that most caps where swollen leaking resistors where chipped and off by a mile. Changed everything blew fuses again PC 5131 rev 0. Even changed out IC Se504L to C504H. In rectifier CR4-CR7 are the same part number but originally two on one side where white, with a red stripe going down the side. Idk what they were. Can't find any info on them. Think I now have damaged pads from reworking. Going to try and re do with a perf board. If anyone knows anything about mystery diodes. Or maybe just a alternative Power amplifier I could drop in instead I would appreciate the help and info.
