Reddit:Electronics

Hi everyone,

I recently published the first version of an open source project I've been working on. It's an electronics part inventory software - completely free and open source (https://github.com/PartPilotLab/PartPilot). I've originally made it for my brother, as he was f*cked up with ordering parts he already had or noticing that he actually doesn't have the part while assembling the project. All existing solutions were either expensive or shit. So I made an alternative. It has pretty much all the most important features and directly integrates with LCSC (but still lacks a bit).
Would love to get some feedback and maybe some of you would be willing to contribute :) Leaving a star would also mean a lot ✨

I was looking for a place to put this where it would be sufficiently on-topic. I hope this sub is the place? I have the above named amp. It had been working (and powered up 24x7) for many years. After a 3 hour power outage recently, it would not power on.

Searching online found many folks mentioning C196, a 220uf 35v cap as the likely culprit. Being powered on 24x7 seems to be a factor in failure as well, but then again, the amp is usually a top choice for installed commercial sound.

Seems like the cap is under voltage rated, at least one person measures ~36v across it. I was told to use caps with a voltage rating of about double the actual circuit voltage in order to be safe.

Long story short, I pulled C196, it failed out of circuit testing, so I replaced it with a two-dollar 60v 10% 220uf cap. That was it, amp works and it's back in production.

Just thought I add my experience as this is yet another case of an apparent weak point in the design of an otherwise very nice amp. TY very much.
