Yup, they were bought for projects which haven't materialized yet.

Plenty of 100nf/1000V caps to be found. This one should work just fine: http://www2.mouser.com/ProductDetail/Kemet/PHE426PB6100JR06/?qs=sGAEpiMZZMv1cc3ydrPrF85GIl804cbNm959%252bOSJvME%3d Cheap too. You can use that PSU but you could have problems. Plus nobody has ever built that PSU there might be massive problems. I just found out over the weekend that the layout software we use has a brand new way of fucking us over with no warning. Stick with the BHSE unit.

I use mine as paperweights...

The spacing is 15mm so go from there.

With +/-400V supplies it is far higher.

Not counting the few thousand units in stock at Mouser?

So... when do you want me there?

Yup and be warned, this is very fiddly. That's why I don't touch the Sigma's any more.

+/-20V doesn't matter the slightest bit.

This is common for the circuit and poses no harm for the headphones.

The 007A/Mk2 is an alternative too, different but also good. That means a more balanced budget.

The KGST and the HV are pretty much the same circuit but the Megatron is very different so the same parallels can't be drawn. This more like a high power version of the SRX That is not the last version but one of the later ones. Here is what a super old one looks like:

I'd like the pads to be a bit higher and thicker but for the price, you can't go wrong. If it is a late SR-1 then the SR-3 pads will work. Most of the parts of the late SR-1's are the same as on the SR-3's. Not so much for the early ones.

SR-3 pads will work but the SR-1 never shipped with those pads. I used the Brainwavez HM5 pads on mine as they are close to the original shape.

I will build a few this year after I sort out the PSU. It will serve as a stepping stone for the T2 project, testing some new ideas.

No build issues I can see. Stax have learned their lessons on the older 007's. To quote an email I got this morning: 'nuff said.

They would probably sell a lot more of them if they fixed that...

The lego is very fitting... There are copper pins that hold them together. Pull them out and the drivers open up. Watch out for the front stator wire which is very easy to break. Yup, 1600$ isn't bad at all. Edit: As for the sound, I still like it a lot. I know I'll have to change the springs and move the earpads to the Mk1 position eventually but I'm digging the extra harmonics in the bass region. It's easy enough to move press the cups towards the head to hear how they should sound.

Yup

Haven't tried the 009 yet but that question is difficult due to the choice of tubes. Only tried the ECC99 as of yet so I have some testing to do.

This one should be very close to being brand new. It arrived sealed and was bought around the new years so very recent. A set from PJ should be brand new from the factory.

That box is 330x300mm or so and I wouldn't go much smaller than that. The problem will always be the height though as the tubes are quite tall so either cutouts for them or 90+mm height.

The box means very little. The oldest ones came in those crappy faux CF boxes but there were also some later ones that used them. Probably just a supply thing. The serial number is under the arc's on the right hand side. Also on the outer box which housed the flightcase. I've done the port mod now but left them completely stock in every other way. I must say this is a very, very good 007 now. As expected the port mod mostly affects the bass and holy hell it is nice. Very deep, controlled which shines when somebody put some effort into recording the drums. It might not be 100% neutral (only more exposure will tell) but this sounds very nice indeed. I'm sure the extra height of the pads is adding something to it but the pads could always be moved to the Mk1 setting easily. The improvements also move up to the midrange, giving it a bit more heft and in true 007 fashion, voices stand out like on nothing else. So as it stands now, a great Mk1 is smoother but this one is more alive. I need to dig out the 009 for a direct comparison but I fear it won't go well for the 009. Imaging and bass really aren't their strong suit which the 007 excels at plus the detail they are digging out is just insane. Color me impressed....

Nope and it sounds lovely with ECC99's and the SR-207 in my test rig. Very little compression as I push the volume.

Well yes as we don't know when the change occurred. Also Stax serial numbers are beyond useless for stuff like this.
