Hi everyone. I’ve acquired some JBL l-166A’s and have been going through them to see what components if any needed to be upgraded or replaced. Last night my father who has an electronics background stopped by to check the capacitors. Visually the look fantastic and when a reading was taken using his capacitance meter the came well within spec. Curious how often this happens? Mind you this is without the speaker being under any load but it seems like a good indicator of the overall health of the capacitors even after 40 years. After measuring, I’m now thinking I’ll continue to run stock caps until my ears tell me otherwise. What do you think?
Below are some pics of the readings being taken.
