I see them on sale everywhere so I'm not surprised. Plus it sounds like shit and the build quality is even worse...

If you just want to have a simple test rig, the price here is hard to beat unless you can find a used Lambda for a similar amount. You would need to reterminate though or use an adapter. The RR1 sounds a lot better though.

That's a hell of a deal and makes me mad knowing how much I paid for my set...

I've never seen anything off the shelf for sale but Vesper can make some for you: https://vesperaudio.com/earpads

I can make an adapter no problem. I'd just have to dig mine out from storage and look at the pinout. I know I bought some extra sockets for these when I made my adapter.

I will be getting both sets of pads and naturally... I take everything apart so expect pics. 🙂 No doubt the normal bias SR-X is a bit bright as they were tuned like that. Stax wanted to bleed off a lot of the bass so the end result is a bright set. My point was more with the importance of the pads as they matter a lot with the close proximity of the drivers. Also when they have arc'ed...they get even brighter.

With the SR-X series the pads make or break them. The current pads Stax stock are actually SR-30 units as the originals haven't been available for a long time. Now for the topic at hand, I have one of these incoming so it will be fun to play with. 🙂

With the SB boxes there is a third transformer inside the unit which taps off the HV side of the audio units and further steps up the voltage. That is then fed into a voltage limited voltage multiplier which generates the bias voltage. With the AC units they feed directly into the bias supply multiplier which isn't very safe these days.

So here I was modding a SRM-006tS to a CCS and noticed this: That is the R+ output and notice the 3 lines coming off it, one going to the feedback, one going to the output resistor and one... going to the other side of the output resistor... One has to wonder just how many of these they have shipped like this? In other news, it was fun converting an original T1 and and this one at the same time. 30 years apart and almost exactly the same...

Crap, I missed that sale as I would have bought 10 sets... I think the dynamic Koss set was A/250 but I could be wrong

Currently, yes. Well if these are even still sold which is rather hard to confirm. They do sound like crap though....

3M has some great stuff that actually works. The name escapes me though....

Well the cause is simple, bio-degradable adhesive which is just terrible and the solution isn't so simple...find something better.

It's been a while but since the Exstata is based on the Stax SRM-1 Mk2 it should just be a balance and offset adjustment. The pots should be matched on the PCB so for balance, put the probes between + and - of each channel and adjust to 0VDC. For offset ground the black probe while the red is in the + output for each channel and adjust to 0VDC.

Yeah, that works just fine.

It's the same headband as the SR-007 so two screws on each side that secures it. Be careful, those are JIS screws so pretty easy to strip with other drivers. Also, anybody want to see the most disgusting SR-007's in the world? https://page.auctions.yahoo.co.jp/jp/auction/s702210988 Yeah...those early ones don't hold up.

Fuck... I can relate to that...

Here is how I did the first one:

I haven't tried a new one in a few years but I might pickup a fresh set just to try out. Speaking of the 007's just see what Stax dropped on Youtube...

Not that I've heard but then again...they have so many issues (and noise) that it might just be lost in the haze.

I found these on the official Stax sale site so a bit more info: So...this is a 007t with inferior tubes (they can handle less power than the 6CG7) and the same 47k plate load. Not sure whey they fuse the B+ on each triode but that's clearly what's going on. Now for the SS: Not enough detail to see the VAS but this is clearly a take on the T8000 and 717 so resistor loaded VAS. You can spot the power resistors behind the VAS heatsink.

Could be. It is clearly a SMD part but most of these are also available in those packages but one wonders why... I doubt Stax are using any of these new fangled "non Japanese" parts as they just switched to On Semi out of necessity but yeah... who knows.

Clearly a jfet input but I didn't see the see any mention of a jfet VAS stage. If this is the same as all the pervious Stax amps (which I'm pretty sure it is), then that would be a 700V jfet...which doesn't exist.

These amps just make me sad... Same basic stuff as the 006t and 727 but at a much higher price. Resistor plate loads at 300kYen? Seriously?

Wrong primary wiring on the transformer? That would point to the high voltages...
