A lot of those filament regulators focus on reducing the differential mode noise. I think the DHT would be more sensitive to common mode noise, because the filament itself is the cathode in the signal path. Depending on the circuit topology, you may or may not be able to bypass the noise to ground. The common mode noise starts from the secondary windings on the power transformer, and gets more complicated with the switching regulators noise riding on top of it. It depends more on the implementation than the pretty numbers in the datasheet.

Looks like I got one

I had recently posted on FB about a visit to an Audio store where I heard a system approaching $500K list price. A hometown friend pinged me and - among other things - said he has a friend/classmate (Princeton I'd assume) who "runs Oswald Mills Audio." Maybe you can get a friend-of-friend-of-friend discount 🤣

Happy Birthday!

Task (HBO) - wow, intense watch...

Three kinds of switching mode filament supplies made in my kitchen. Right: Traco brick, only 5V with some fine adjustment, designed by Kevin Gilmore and slightly modified by me. Left: DC-DC Step Down Converter XL4015, adjustable voltage and current limiter, have used it for 2.5V to 6.3V. Middle: TPS62913 Low Ripple Buck Converter (green board) My own design but done with help of TI datasheet (all info needed is there). Copper color board is an Elekit regulator with 2A3 and 300B auto detection. I’ve added a trimmer for fine adjustment of voltage. All three seem to work all right with my electrostatic amplifiers. I also have Pete Millett, Tentlabs and Coleman filament regulators. They are all bulky with heat sinks and produces a lot of heat. Yes, I do agree. Yes, at some point it (probably) will be a different matter.

Happy birthday you Dusty Chalk!

Happy Birthday, Peter!

RIP AJ.

My favourite band in the world had their friend Clint Carney make a video for them as part of their Kickstarter. The song itself already tugged at my tear ducts, it's so powerful, and the video is everything I would have wished for and more: For those that don't know, or haven't followed Al1ce since 2020 (like I do), it is very rare that Tash goes without her stage makeup. I think there is meaning behind that choice in the video... For reference, the previous video that Clint Carney made for them is also a favourite:

😭

No, I don't think so, but that's okay, their fanbase has grown by like a Brazillion since 2020, and I'm happy for them for that. Thanks everyone!

That's how I felt after hearing Oswald Mill Audio Imperia speakers at his loft space in DUMBO years ago with JP#s. Big speakers with intimate live sound.

On No Kings day, Claire and I made an exception for Kingfish, aka Christone Ingraham. He's an amazing blues guitarist and a great singer to boot. I was very happy to hear some great blues and if the video works for you, it was a blast when he walked out into the audience while playing and ended up two feet from me. IMG_7503.mov

Joseph Crowe Audio horns. Heard these at an audio show last week and they've basically wrecked everything I thought I knew about audio and redefined what is possible. The performance ceiling in high-end audio is far higher than I ever imagined and much closer to live sound than I thought.

Happy Birthday!

The medium wears great, and that tobacco brown is a great color.

Happy Birthday, Peter! 🟪

I'm not sure anyone cares, but here are even more pictures of the jig demonstrating the various uses. Tenon, mortise, bridle joint, etc. Splining miter joints L-fence for ripping straight edges or long miters And a gratuitous shot of Steve on Grindr

^ Same. Very sad to hear. RIP

That's sad news. He was fantastic when we saw him with Hiromi too. ☹️

RIP Anthony Jackson, superb bassist..... I got to see him with the Hiromi Trio Project, so incredible; both Karen and I loved him (all of them), and she wasn't even a jazz fan. https://www.guitarworld.com/artists/bassists/anthony-jackson-dies-aged-73

Happy Birthday Dusty! Did you get a greeting (card, e-card) from Al1ce?
