With my newly found soldering skills, I have been trying to ressurect both my out of action Grados, an SR80 and an SR125. The left driver was out on the SR80, the right on the SR125. Now, I took the 80s apart and simply resoldered the detached wire - bingo, all done and they wsork perfectly now, which I'm over the moon about as they put my HD598s to shame in many ways.
That was last night. Tonight I moved onto the 125s. Now, to my surprise, they were working on both sides, but just an intermittent cutting out on the right which didn't seem related to me wiggling the wire, so was a bit strange. Anyway, I opened the cup and found both wires attached. Through some radical experimentation, I found that when they were not working, I could get them to work by either:
a) touching a metal key to the back of the driver
or b), blowing gently into the driver from the front.
I couldn't decipher what the problem might be at all, so I decided to detach the wires from the driver and resolder them. This hasn't worked and the driver is not responding at all now. I'm hoping that someone with more knowledge and/or experience might be able to chime in and give me some advice on the next step, beyond sending them back to Grado or calling them off as a lost cause! I'm really aching to get them working, as for the few moments they did work, they sounded just awesome, especially with the hole-punch mod done to boost the bass!
Any help would be much appreciated and I'm thinking this is the best place to ask!
Many thanks in advance!
