Revisited the little Thai spot we used to like in Esher, Surrey last night. Had the lamb panang curry. It was jolly savoury!

Aforementioned pig’s trotter.

Did this today. Positive golden reference regulator. I managed to make a Kerry device in my kitchen but I think he is pushing the envelope now. I’ll try to make negative regulator as well and if this succeeds I’ll put them in a T2 PSU. Dark picture so you can see the small red LEDs on the board. Hope the small GRLV hit the market soon.

I'm getting better with Eagle, so here's an updated version of the GR78xx boards (still need the GR79xx version). This version supports higher voltages and more current (some infamous designer wanted that ). The board is the same size at .8" x 1.16". GR78xx.xlsx GR78xx-Gerber.zip And some pics...

Maybe they're one-way glass? XD

After a few weeks burn-in period of this little beast, I found it's very relaxing to listen to. I can hear more juices coming out and the STAX 009 just doesn't have that analytical sounding cliché to my ears. It also enhances the soundstage and life-like of Focal Utopia makes it way more enjoyable to hear. This is a push-pull design tube Headphone Amplifier/Preamplifier attempting to achieve the true high-performance of headphones from Dynamic, Planar Magnetic to Electrostatic models. I've gotten a few PM's asking about the schematics and stuff so I decided to open a thread to discuss more here. a few interesting measurements of the amp at R = 6Ω DT-HWT Headphone Amplifier/Preamplifier schematic: DT-HWT Power Supply schematic: ===================== Inputs – it has two sets of RCA inputs. Output – it has different outputs, provided on a number of different connectors. On the amp front is a TRS ¼” unbalanced jack, and balanced headphone outputs on a single 4-pin XLR and a pro bias 5-pin Stax headphone jack. On the amp rear, there are two sets of 3-pin XLR and RCA preamp outputs. Both sets can be used at the same time if desired – for example, you could feed a power amplifier from the XLR connectors, and a subwoofer amp from the RCA connectors. The bias voltage settings on the separate power supply unit are used only with electrostatic ear speakers (> 100K Ω impedance). You can select whichever bias level sounds better to your STAX/HE90 models from 230-500-580 up to 620 V DC bias. Tube complement for the amp unit is: matched pair of EF86/E80F/6D8 & matched pair of 12AU7/5814A/E80CC/E82CC & matched quad of EL95/6AQ5 Tube complement for the power supply unit is: matched pair of KT66/KT77/KT88/6550/6L6/EL34/350B/350A & one 6080/5998/6AS7/6H13C/2399 Look forward to those next iterations/variants from you guys soon... For the meantime, I keep on rolling 11 tubes to find the best combination that suits best for different music genres

He's rich and he is connected, he will never see the inside of the Big House.

Pretty sure he meant charging or Charo-ing...kochi-koochi

Lebanese/American steak and cheese Let me explain -- I go to this Lebanese restaurant all the time, Raouche Cafe. They sell things like kabobs, shwarma, stuffed grape leaves...and steak & cheese. It seems kind of odd on the menu, but there it is. I really love the beef. It's practically steak. Plus they marinate it in this secret recipe, and it's just divine. So I asked him to make me a steak and cheese, only with the marinated shwarma beef. They did. This time, I asked him to make me the beef shwarma wrap (the steak and cheese is a wrap, too, that's the one Lebanese thing about it), only add lettuce tomato grilled onions and cheese, I.E. a hybrid Lebanese/American shwarma beef & cheese. It was so fucking good. SO FUCKING GOOD, I was giggling.

Silly, that gel is ubiquitous in California. It is used by soccer moms to convert A cups to double D cups.

Are you stuck in JFK?

The perspicacious would opt for perspex........ I can just see the aftermarket crowd going wild with this one...... Besides the usual plethora of aftermarket cables, there will be:- Coloware will have a range of colored covers.... There will be a plethora of different wood covers. Edstrelow will have a pattern of sorbothane to make these Stax killers The Hifiman HE-6 crowd will break out different felt fazor mods. Anaxilus will have 3 different mods to get rid of the echo chamber cavern effect... The newest mod will be to coat the inside of the covers with teflon to make sure even the sound doesn't stick... etc, etc, ad hoc, ad addendum, ad astra. ad nauseum...........................

There's no accounting for taste. But seriously, credit where credit is due - all I did was update the original Stax circuit. Whoever designed that circuit deserves the credit.
