Unfortunately that’s the part about being good at your job that sucks - all the difficult shit lands on you because you’re the one that can handle it. Doesn’t make it any easier or fun. We work in different industries but I feel your pain there.
This is a candidate for entirely new PCB’s. I couldn’t imagine the hours required to repair that damage. It’s going to cost more than the thing was ever worth.
Hi Brad, with the carbonised board you can fix them by scraping out the carbonised sections and putting tape on the underside and filling it with expoy resin then link some wires across where the tracks burnt and epoxy it again over the top.
You are one hell of a tech taking this on!! I would have called the owner and told him to pick it up, as the fix is so labor intensive it's not cost effective to fix. There are some owners that have a big enough attachment to their equipment that they're willing to pay, which is ok in my book. I can't wait to see the other two videos to this series. Thanks!
I have one of these on the bench thats been kicking my ass. Clean channel has horrible hum and is very low output. Also when engaging the "pushed" switch the clean channel cuts out to just hum. Checked over a lot of stuff but one thing I noticed right away was some traces and wires had been cut, the cuts look well done and probably from the factory but I couldnt be certain of that. Have you ever encountered this problem before with any dual or triple rectifier amps? Have not had any luck tracking the issue down but think it may due to a switching FET being cut off from the rest of the circuit from one of those said cuts, but then again the relays click when the switch is thrown for "pushed" so I am not sure
