I love it when that happens!
I acquired a pair of Shure KSM32’s a while back in a trade for studio time. Thankfully, the guy brought them before we started. The original deal was for $600 of studio time (totally in my favor, yet no one was taken advantage of). I didn’t even really want the mics, figured I’d sell em if nothing else. Upon receipt of the mics, I immediately tested them as soon as I could (at the end of our first session) and one of them wasn’t firing. The deal was then readdressed, dropped to $400 in studio time as I’d have to repair it.
Shure is actually cool about their repairs: they have flat fees for any product, and repair. If I were to ship it to them, give them $96, I’d have a working mic.
But, I wanted to see if I could fix the sucker (Probly a stupid cap in the power supply section, right?). Nope. It’s aaaall SMT. Dang. On the shelf it went until I had $100 to play with.
Today I opened it up again, just for one more look. Maybe there’s A solder joint I can futz with! Turns out, there are two PCBs: one for the actual guts, one for the pad and roll off switches. The second one (harder to get to without actual disassembly), does have some solder joints and the input from the capsule goes through it all. So I took it as apart as I could without desoldering.
Turns out, there’s a slide in connector between the two PCBs. I plugged in the mic while all the guts were in my hand to see if wiggling now accessible wires would indicate a bad solder joint. And! It was stinking working! It was just a connector that was tired at life and needed a little massage!
Sometimes, things just need taken apart:)
