Hello all!
I'm running across a problem unfamiliar to me until now. I've had the PortaPro's since 2010, and have had no problem so far. I've changed the plug and rewired them multiple times with success, and had no isues until today.
This morning, one of the drivers stopped working. After opening them up and checking, the most obvious thing showed up (a dissoldered cable).
Once again, I soldered all of them back in their position (since I was doing it for one driver, and in order to avoid a different cable lenght, I decided to recable both). I tested there was continuity between tip, body and ground from the plug to their respective drivers/lead.
However, there was one little thing that posed strange to me. Everytime I resoldered the drivers before, there was a faint continuity between the 2 leads in the driver itself (between those 2 leads which are supossed to be soldered to either tip/body and ground).
This time, there was no continuity. When I got everything back together, no sound came from the speakers. I retested the continuity between the leads (flawless), and that faint continuity between the 2 leads was still absent.
Unfortunately, I can't get the PortaPros to come back alive again, and I wish for you guys to help me a little with this.
Actually, it would be great if any could provide some tips for testing the drivers, or even better, a schematic of how should the leads be related to each other in the driver. As far as I know, a little speaker (as the driver is) should only have voltage and a reference, there shouldn't be any other "special" structure inside. That's why I'm still confused about what could have gone wrong, or what exactly is going on with my drivers.
Any help would be appreciated.
Thanks in advance!
