[QUOTE="1200GXman, post: 1123937, member: 17884"] [ATTACH type="full" width="857px" alt="amp face.jpg"]18437[/ATTACH] [ATTACH type="full" alt="bias pots.jpg"]18438[/ATTACH] These bias pots I am very tempted to replace. They have some kind of white glue to hold them in place after factory ajustment and it still looks uncracked. Never been adjusted after it left the factory. Is it recommended? What would you guys recommend as replacements? [ATTACH type="full" alt="ceramic cap top.jpg"]18439[/ATTACH] It looks like this big saucer cap right bottom leaked or sweated. Will rather replace. [ATTACH type="full" alt="ceramic cap bottom.jpg"]18440[/ATTACH] Saucer cap bottom view. You can also see the white residue I want to clean. Don't know what it is because this amp was never at the coast as I understand. I inspected with a magnifying glass the bottom and all looks good but will do it again over the weekend to check for cracked solder joints. [/QUOTE]
