Beefy Posted November 26, 2009 Report Share Posted November 26, 2009 So after reading all 271 pages, my head is ready to explode....... I picked up some SR-Lambda's on this very forum. They are in good condition but still showing their age, and I would like to give them a bit of a spruce up. So I am just going to spill out all the info I have collected about such an endeavour, and open the floor to any corrections or comments! Before I take anything apart, my understanding of the construction of the earspeaker is as follows: 1. Pads, also containing the 'mesh' that spans the speaker opening. Easily replaced. 2. A thin dust cover. Should remain in place. 3. Driver assembly. Should probably not be touched. 4. Backing foam. For dust protection and dampening, should remain in place. 5. Mineral wool; further dampening, can be removed if desired. The current pads are OK, but have a couple of small splits forming and are perhaps a little flatter than they should be. So these seem to be the prime candidate for replacement, and any current Lambda pad can be used: 202: Same black colour, but a different material to the old pads. Better? Worse? 303: Grey, same material as old pads. 404: Shit brown colour, same material as old pads. 404LE: Nice black leather, but expensive and 'thinner' than the other pads. All of the new pads seem to have a soft cotton mesh over the speaker opening, instead of the older plastic mesh. The foam and mineral wool can be replaced if they are starting to disintegrate, but this is generally not necessary. The whole headband assembly can be easily replaced with a current model one; same colours available as for the pads. But they are ridiculously expensive for what they are, and will lose the original SR-λ branding and serial number. Is there any way to just replace the fabric part of the headband? That is probably the only part that actually needs replacing. The cable has collected enough nicks and kinks in its 30 years that I am seriously considering replacing it - IF I can get a suitable replacement. Now I don't trust myself enough to never accidentally plug the phones into a pro socket, so is it still possible to get a replacement cable with a normal bias plug? If I do replace the cable it seems to be able to be done without opening the driver itself - it sounds like there are just three 'external' contacts. But I have to make absolutely sure to protect the driver assembly from spitting solder and flux, which will just melt right though the diaphragm. Lastly, places to potentially buy all this crap......
