K1000 Recable Guide

Ok, so I'm working on the guide revisions for the other style PCB, and I've gone ahead and done some testing comparing the different PCBs and drivers. Both types of PCBs seem to have the same effect on the sound (surprising for AKG), which is not a notch filter or anything like that, but reduces the upper midrange and treble output by about 3-4dB. The drivers themselves do measure and sound different (the older one is better kthxbai), but not the PCBs, which I can't really see a good reason to remove them unless you're wanting more treble out of the K1000.

Interesting.

Ok, for removing the other type of PCB where the two solder posts are further apart, all that needs to be done is use some desoldering braid on each one, then lift it out by tilting up the side further from the driver and pulling it out at an angle like that. If you try to lift it straight up, there's a very good chance of severing one of the voice coil wires, which I discovered the hard way while experimenting with different ways of removing it. The desoldering braid works very well with this, because the side of the PCB isn't plated, just the face of it. Depending on circumstances and your technique, you may end up with a very tiny bit of solder keeping the PCB attached to the post, which can usually be dealt with by gently tilting the PCB up and down (in the same manner as if you were tilting it to remove it), and it should break loose with little effort. Do not use any significant force trying to get it loose, because it's very likely you'll end up jerking it up once it comes loose and ripping the voice coil wires off. Reassembly is a little trickier because you have to put it back in with the same angled method (while getting the wire to stay put in that channel underneath the PCB), but with a little patience it isn't too bad.
