It's great to hear that the amp is up and running again. Working on SP amps does give clusterfuck a whole new meaning...

To open up a SR-007 you simply pull off the earpads and loosen the screws in the black backing plate. That was the easy part, getting them back together isn't...

I'll also be making some different bias boards soon to use in the ES amps which will be adjustable plus have a voltage divider. Not as fancy as the DC-DC units but should be quite a bit cheaper and smaller.

I really like the cut up Uberbias board and the air mounted fuse connector. I really need to order up the parts for the Vulcan though...

Being OT is the HC way!! I got both the disk and the new drive from the Meridian distributor up here who ordered it directly from them. All you need is a null modem cable and the software Meridian have up on their site. It's been a while but I believe the player went from being V1.02 to V1.52 or something like that.

FIRE UP THE VULCAN!!!!! The bad part about Riken resistors is that empty feeling if they were to burn up...

You can use the newer DVS drives in the G08 if you upgrade the firmware. Before I sold mine I replaced the drive and was sent a new version plus a disk with the firmware.

Perhaps they just shipped it with the Japanese power cord. They are almost the same after all. If you are worried then just replace it with a any IEC powercord.

If it is a Japan model then it is quite normal. They don't have ground in the receptacle over there (hence the ground lug on the back).

Moar broken stuff = moar tech skillz!!

Yup, find the speaker you want and build from there.

It's been too long and now I can't find the schematic. The caps in the bias supply are rather big at 1uf so that could be a factor.

Yes and no on that one. I've owned 4 ET-1000's and only half played off a Stax box perfectly while the others had issues with the bias supply. No worries though, I have the Beyer bias supply schematic somewhere around here if you need it...

If the 909 mono's are just bridged stereo amps then they should be able to do it.

The ET-1000 is a great mix of the Stax SR-X Mk3 and the SR-Lambda with some twists of its own. A truly great headphone...

Sure is. That's the best part about P-P tube amps, you have to do the chassis work first before anything else.

...so I should start to assemble some PCB's for you then?

Any Stax II model is export so if you were to buy from Japan then they are A models. There is no difference besides the A models only being available in silver and being wired for 100v operation. That can be changed though with a bit of soldering. It's well worth it for the huge savings.

Quite a bit actually... There are a couple of possibilities, most of which are based on the earliest Stax amps such as the SRA-6S. It's such a rats nest that the pictures make it almost impossible to decipher. How about Al brings the amp to you next time you meet and you draw it up for us... no?

Singlepower and RWA... isn't that the definition of fail? Ohhh and damn you Justin for not allowing me to have an all silver BHSE. I do have this sandblasting rig though...

It's a SR-Alpha Excellent Pro cable. The gold pins prove it is a PC-OCC cable and that is the Gamma/Alpha strain relief.

Happy birthday!!

You need massive amps for those S-L's since the M3's are hardest units to drive. I heard older A-1's and they are sublime to say the least...

The big ES-1 is taking up all my time plus some PCB work on the side. Once the big ES-1 is up and running then I can start work on the mini and draw up the PCB. I'll probably draw up the Egmont as well since it is so simple with feedback and all.

Happy birthday!!
