Cheap....

The front end draws almost no power so a stock KGSSHV psu setup should be fine. To get a 300V output you need a transformer with far lower voltage, you need to adjust the voltage divider and set the zeners to 350V.

Get cracking!!! We expect results by next week!!

A F5 in this chassis would run very hot indeed.... There is a larger version of the same chassis which might work with the bias turned way down. For the HV, chassis like this means I can turn up the current and I have some even smaller ones in mind which would have to use a simpler PSU and lower voltages. Running at +/-400V opens up plenty of options for output devices in current production and MOAR CURRENT!!!!

I got the Dell Venue 8 for Christmas and while it utterly kills the ipad for my needs I wouldn't even try to give one to my mom. It's quite small and dinky and the Win8.1 tablet stuff only goes so far and then you left with navigating standard windows stuff via the small touchscreen.

Perhaps it is a time the mafia fixes the squeal issues once and for all? That said Koss should really update the design, it's been exactly the same since at least 1989...

Nope, bought off ebay.

That's excellent news!!! Speaking of offboard... say hello to the new super tiny KGSSHV's.... This is a new version of the offboard design I did for my own use. Cut down in size as far as it can go and 2SA1968 only. The power supply in the pics is a version of the BH supply as even the KSSHVk PSU is roughly the same as the entire chassis. That said, I'm putting the finishing touches on a version of the HV psu which will fit in there...

Well I can attest that a Lambda driver in a HE90 shell sound pretty spectacular. My Omegas now just gather dust...

It has a DC plug on the back so it has to use a switcher to generate the HV. Whether it is regulated or not I have my doubts as Stax only regulate when they absolutely have to. In the SRM-300 they were running the output devices right up to the limit

Happy Birthday!!!

The amp slotted between the SRM-252S and the 323S. USB dac built it... Oddly it says SRM-212 on the back....

The G-lite is an excellent amp for something so bloody tiny. For Doug, I just got off the phone with my friend who has my L-2 on loan. He couldn't praise it enough with the HP-2's but he had one request, an electrostatic amp with the same basic chassis design. So Doug, get cracking!!!!

99% chance that it is made in Japan. The Chinese are all too aware of the benefits of doing that...

At least it's a nice looking Beyer...

Sure but something like this might do a lot more harm than good.

Also, how were they used?

There is a solid piece of PVC film that should keep everything out. If that fails then the drivers are pretty much scrap.

I never bother to replace it.

I really don't think Stax care at all about competition unless they are trying to leach off their work. It's often been stated that the SR-Omega was a reply to Sennheiser releasing the Orpheus but I've always understood it as a last ditch attempt to save the fledgling company from collapse. They had been doing a mammoth research project to look into what truly made 'stats tick and were simply running out of time. The Lambda is from 1979 and it does show its age. I guess their biggest problem is what to replace them with as if they go with the flat planer stuff we have now then a lot of the soundstage will go as well. The Lambda frame is in it self a stroke of genius as it creates a semi closed space which allows for some reflection, hence creating this sense of air. It's naturally a trade off but their real problem was always how the drivers were put together and mounted to the baffle. With the x07 series this has been drastically improved so the best way forward would be to drop the silly model distinctions and go back to 3 models and have them all black. One could be gray but the brown and green have to go... As for an improved look, what they could do is change the frame to a more done shaped structure and replace the plastic grill with metal. I do think Edifer should at least attempt a cheaper line of 'stats made 100% in China. In Stax they have the expertise to make them properly and of a consistent standard but they should not be branded Stax at all. I'd use the Stax name in marketing and such as a way of showing the heritage but that is it. It's better than some crap pushed by shills and people with very little exposure to 'stats we get from China now.

It's just open cell foam, nothing really special. You could also just buy some fabric intended for speakers.

I truly don't get the interest on HF over the new Jade. Just look at the prototype, they are still doing the same old stupid shit (no Stax plug for instance) and we all know it will be very, very expensive. No leather pads which makes no sense at all. Now I'm the last person to defend the King Sound lineup but at least their headphone sounded better than the Jade stock and was 500$. They also managed to make proper cables and the whole assembly is solid enough. They are also replacing all the H1's for H2's free of charge. Still I'd rather have a 207...

The earpads just require some trial and error but you'll get the hang of it

Happy Birthday Frank!!

You can remove the elastic mountings and shorten it a bit. Just two screws on each side.
