I am still fighting a potential audio amp problem. Very odd that the thing went from a clicking noise in the speaker, to working fine, to now making a loud hum at the speaker. The finger is more or less pointed to a termination or cabling problem but I cannot ignore the amp right now.
the caps "look" minty but wondering if there are ways to tell if caps are dried up? Do I need to remove from circuit? If so, will a simple capacitance test tell the story? There is 8 of them and would rather not pull on a whim. The amp is 10yo but was running great and not run very hard. These caps are all 820uf, 400V IIRC.
