You’re right David; it can turn into an endless circle! And rather than removing and testing all those passive components, safer and easier to just replace those too. Oh, and to ensure there’s been no damage caused to the PCB, replace it also with one of those cute, high-quality Chinese copies.
Repairing faulty DC-coupled amplifier boards is a mug’s game, and makes no sense. Just build new ones. Especially as this is such a relatively simple matter with the 303.
