Nope, sold them without the transformer box. I had no use for it (and nobody wanted it) so I thought I could use the box for something else.

Worked on my longest running DIY project, how to cram an amp into a Koss ESP10 energizer chassis. Not easy but it will be some form of the differential amp (ECC83's and 7n7's) with the old KGSS psu (i.e. what PCB I had at hand). Should be a cool little balanced amp if I ever finish it (2+ years and counting now)...

I never measured the stock T2 knob but its size was pretty absurd. 1x1.5 would be cool though.

That's pretty much what I think of them, the ESL57 is limited but what it gets right, is spot on. The ESL63 is more versatile and clearly a "better" speaker if it doesn't have the magic of the 57. What I'd love to hear is the Stax F-81 which is supposed to be even better in the midrange (and even more limited elsewhere) and a fully rebuilt 57 with thinner diaphragms.

Moar bass is easy enough to produce by adjusting the crossover a bit...

You don't need to change the bias and some like the effect while other don't. To change the bias in a KGSS/BH then you need a good meter (Fluke or similar) and preferably with those hook probes. A trimpot tool is also a good idea since if you drop it, nothing will short out. There is a trimpot in the PSU which you will adjust and you place the black probe to ground while the red probe is connected to one leg of the ballast resistor (located next to the tim pot). You place it on the end of the resistor which faces the trimpot as the other end will just give you gibberish.

I haven't opened up one of the new speakers but from what I've heard nothing has really changed. The brace is there but it doesn't do a whole lot since the panels are essentially floating inside the speaker.

The SR-Lambda is in high demand and short supply so probably not.

The largest Mouser order I've ever placed plus PRP and Mills resistors for the T2.

I wouldn't say my fellow mafia members are beating him into submission but one has to make a choice, endlessly follow the dynamic dragon or stop and try electrostatics to see if you like that sound. The SR-007/717 is something that makes it easy as they will go quickly on the used market and could be the last system you'll ever need. As for SP amps, if you know what you are doing then you can easily turn them into something great with a bit of work. The question of value does come up though if you'd ever want to unload the amp later on.

The Mk2's have one Pro and one Normal bias outputs.

That's not bad and kudos for getting through to them. Most aren't so fortunate... Never tried gorilla glue, no such thing exists here. I got mine here locally but can't remeber what it was called, it was a large container which I had to cut up into small quantities so that it wouldn't set.

Getting all those pieces to fit perfectly together is a mammoth pain in the arse when reassembling the drivers. The polyurethane just makes it worse but it is the best adhesive for the job.

You can remove the black mesh from the stator assembly but it will take some tricky gluing to get it back together. See here how the drivers/baffle is built up on the newer drivers but the old ones are essentially the same. The foam will always crack on the older phones. Stax does ship out replacements to the distributors but I usually just remove it, with no audible effects to these ears.

Please get a quote on the sockets for us. The socket you sent me requires next to no force while plugging in the cable so nothing to complain about there. Ohh and I do have one of those items you were asking me about earlier.

The drivers are glued onto the baffle so no way to move them. If the foam in the earpads is gone then you you have a good view of about 95% of the front dustcover.

Most excellent!!

Peter Daniels uses these in his builds so contacting him on DIYAudio could help. I quite like this Vampire part, I have a few which I bought from Justin and I could measure them for you.

Happy Birthday!!!

They are just ESL63's. Same design except they have some major issues putting parts in the right place on the main PCB, at least on the two pairs I've seen.

I like the SR-Omega/007 even moar...

Moar DACSES are needed?

Cheers

Needs that tacky gold plated SP amp.

Yup, you are right. Brand new (preferably not even available yet) or OOP stuff.
