I recently bought another pair of K340's for a little mod project.
The owner sold the pair mentioning one side had a lower volume, so thinking it was most likely a broken cable or solder joint, I took them.
Now, first I re-cabled them using some canare mini starquad and did the default PCB bypass mod. I completed the unit and had a listen and.. bleh, very dark muddy sound. Cutting the wires to the PCB/electrets made the issue clear, the sound did not alter so there had to be a problem there.
I once again took them apart, soldered the electrets from the PCB, reflowed all solder connections, replaced the tiny cables with 24awg SPC. Placed and soldered everything in place again and.. the right side seems to be working fine. If I test some higher frequencies (8-14k) the right side seems to be handling fine if just a tad quieter then my NOS K340. But the left side is very quiet and not capable of the same range and sound pressure as the right side.
So, is my electret broken? Or could there be another issue like a bad resistor or anything alike.
I still have spare parts from my second K340 which had damaged PCB's, so I actually do have spare electrets if its as simple as replacing those. If so, should I just replace the pair or is there no difference in sound between versions (grey, green, red dynamics might have different electret too?).
But before going ahead and soldering (again..) I'd rather get some input.
I really seem to be having bad luck with these
So if anyone could give his insight on this, appreciated.
