Ever hear about a buddy who had a similar issue? My friend was trying to fix an old stereo and his digital meter said all the parts were good, but this beat up analog one he had kept showing a shaky needle on a single capacitor. He swapped it out just to see, and boom, the thing worked perfectly again. I mean, digital readouts are clean and easy, but sometimes that old needle movement tells you something a number just can't. Idk, maybe it's just me, but that's why I get not wanting to ditch the analog tools.
Yeah, read a forum post where a guy was troubleshooting a flickering LED driver. His digital multimeter showed steady voltage, but hooking up an old analog meter revealed tiny rhythmic dips that matched the flicker. Digital just averages things out sometimes, but that needle jitter tells the real story. He traced it back to a bad voltage regulator the digital tool completely missed.
