  22. Sorry this texte is in French Une réparation due à une défaillance des condensateurs électrolytiques est devenue un phénomène banal, inhabituel dans les années 80. translate: Repair due to electrolytic capacitor failure became commonplace, unusual in the 1980s. https://qastack.fr/electronics/253976/what-happened-to-electrolytic-capacitors-in-the-21st-century on the old capacitor you could reform the electrolyte https://www.carnets-tsf.fr/condensateurs-anciens/reformer-les-condensateurs.html sorry in French. But, as I mentioned in this thread, everyone has to decide for themselves. By cons I retain your idea of changing the regulator, If on the capacitors we are not entirely in agreement I tell you very good idea😉
