AES - Very quiet left audio through headphones after recap

I've encountered a weird issue after recapping my AES; the left audio channel through the headphone jack has gone extremely quiet while the right channel works perfectly fine. All of the caps are of great quality (a mix of Panasonics and Nichicons) and soldered properly, and I didn't damage any traces or pads while desoldering the old caps.

I think something's up with the headphone mixer because if I tap the audio before it goes through the mixer (which is how I have my stereo audio mod wired up), it works fine. Any ideas? I'm not particularly torn up about this since I'm not using the headphone jack for audio, but I would like to have my system working 100%.

Clean the slider with a qtip and some contact cleaner. The tracks are probably dirty.

The volume slider is super clean and I even went over the solder points for it just in case. Still no joy.

Are you 100% sure you haven't reversed the polarity on one of the caps?

How did you desolder the caps, it's possible there's a broken trace or broken via.

I'm 100% sure they're in properly, that was one of the first things I checked after the issue came up.

I used a desoldering station, no way would I use desoldering braid or a solder sucker on my AES.

Check the nichicons because I remember someone saying that the quality control on those are bad so you might have different readings from each cap.

I finally got around to fixing this 9 years later, it turns out that the 2066 amp was faulty. Just replaced it and I've finally got my left headphone out fixed!
talk about a bump from the past

So in the end it wasn't a RECRAP problem.
Is #recrap going to become one of those obscure memes that only a few retrogame modders know? We need to make this happen if it hasn't already.

It hasn't happened yet, at least to my knowledge...

maybe in ten years if we find the current caps develop terrible issues

#recrap is for when you bought into the hype and unnecessarily recapped a system, only to screw something up.

Feels like something a Voultar-type tech would say to drive business or an elitist term to mock someone for even daring to try. I'd say learn to solder and consume as much information as possible, and lose the fear of touching the insides of old videogames instead of making it taboo, and the fear of doing something unecessary/wrong.

While I like and generally agree with the sentiment, I've screwed up a Famicom, an AES, an Xbox and a GameCube before I had the ability to fix them myself. So I can't really cosign that. I've since gotten better and been able to fix most of those. It might be because I am particularly sloppy and impatient, but I'm still very wary about replacing more than a few caps.
