That's the metal mesh your ears are touching and I wouldn't recommend removing it. The new pads come with a cloth insert which is put inside the baffle cutout so you could probably DIY something similar.

The foam mesh or the metal mesh? The metal is a part of the drivers but you can just leave out the foam or put in some acoustically transparent cloth. I use Autoglym Vinyl & Rubber Care (made for cars) which has a mild gloss and works a treat on old Lambda parts.

You should be able to add some filler to the new earpads to make them more comfortable. The old pads could be just fine though and get some vinyl renewal stuff and wipe them down with it. Makes them a bit softer and is also good for restoring the rest of the Lambda frame. Just make sure it isn't the glossy stuff...

Excellent.

The headphones are: Pads, Baffle Drivers (all glued together) Mineral rool (which you should never have to replace) Foam lining Cups The SR-202 pads use a slightly different material to the old pads but it is close enough. The SR-303 and 404 pads share the same material. All of the new pads are thinner then the old ones. The headpad is easy to replace, two screws on each side. I think I even have a black one stashed away if you should ever need one. Any replacement cables would be 5 pin but the SR-202 will work. The drivers are soldered to the cable so extreme care is needed but use common sense and you will be fine. Add KuboTen.com to that list. Craig is one of us and is more then fair with regards to pricing.

Why not take one for the team. It could be an interesting amp if a bit too expensive for my tastes.

Moar amps in moar silver makes me moar happy...

Do you have to pay extra for the chipped paint and rusty screws?

Mmmmm drinking....

The SR-003 will tell you a lot if something goes wrong. Wrong bias voltages scream at you and it's great for picking up hum.

I'll see if I can't find the pics and upload them again.

Happy Birthday!!!!

They will work off any Stax jack since they don't need a bias supply.

Should be but I couldn't find it...

I even posted a how-to guide of sorts here on how to convert the Sigma's...

I much prefer the way of taking a crappy SR-404 with a SR-Sigma and turn them into two awesome headphones.

The T2 DIY is still a ways off but it will be ready before CJ'10.

I was never that impressed with the Sigma Pro, it always sounded a bit out of control and the bass suffered. The SR-Sigma and Sigma 404 can rock with the best of them though...

Will do!

Happy Birthday!!

...and here I was looking for the power input for the bias supply. ESL's would take up too much space and these are inefficient enough for me to buy some serious grunt to drive them which could later be used for some 'stats.

Made 1500 muffins, not a whole lot of fun to do on my day off...

Too bad for them that Lewis was canceled...

Spendor S3/5SE's I was too lazy to take a picture of my set but they look exactly like that. Power hungry beasts for the soldering rig.
