HeadRoom Portable Desktop Amp power supply question

According to the internets. Another version of the same has a line to the Center as positive. On Ebay - some one is selling one with this wall wart power supply Looking it up on Mouser - it is indeed - Center Positive. (unless he is selling it with a supply that would make it not work) But I think it is safe to say - Center + - Yesterday

A frendly Head-Caser has kindly lent me four EL156, So, I made myself some EL156 to EL34 adaptors. Here a Megatron SS CCD something with the four EL156. Same friendly fellow has built himself a couple of filament supply for DHT similar to the one in above post. -

Two things: (1) This time of year (we're picoseconds from the solstice), the sun does some funny things. (2) My CZJ 135mm F/3.5 Sonnar is one of my favorite lenses, full stop. I describe the images it renders as "handsome." Everything is sharp, colorful, and has the right amount of distance between subjects. In a different universe, I might use a 135mm on a medium format (Hasselblad makes a neat 135mm that'll set you back about 5 large.) It is not the narrow FoV that I like, it's what is to my biased eyes the "correct" amount of telescopic compression. To wit: Note the birds in the upper left corner. Earlier, I was capturing fall colors with the Sonnar: Also this photo got into Flickr's "Explore" section: Nearly 5000 views and 150 favorites later. TBH I find the whole thing kind of silly. Longtime listeners may recall me mentioning that Explore is heavily botted and most of the photos that end up in it are eye catching, but not particularly good. TBH that's what the above is, I think. The Sonnar's bokeh is quite good and the little cedar tree is tack sharp. With that said, the framing is nothing special. It's just a snapshot with a shallow DoF. The Sonnar is a great lens. Flickr is dumb. Bonus, previous photos of mine that I have made it into Explore: The pond next to Edgartown harbor. 2020 rework of a photo I took in 2006. IR version of the same area, 2013. A bungalow, across from Cannonball Park. As I said, eye-catching but not necessarily good. Next time: Cats, squirrels and whatever I get up to with some new glass (more on that later.) -

We caught up with one of the kids who sang on 'A Charlie Brown Christmas.' He's 72 now. https://www.npr.org/2025/12/19/nx-s1-5640171/a-charlie-brown-christmas-christmastime-is-here-peanuts-schulz

Does Broadway count? New music for this revival by Benny Andersson & Björn Ulvaeus of ABBA fame, with lyrics by Tim Rice.

This is the statement, translated: ...so I don't think they are going to replace them. The Shure KSE's are also discontinued with no replacements that I've heard of.
-
Do we know if they discontinued the 002 for good, or are they bringing out another version at some point like with the 007? The IEM world has gone off the rails in the high end and Stax could do some disruption if they just fix what was wrong with the system, which is mainly comfort. I never tried the 002 but the old 001 mk2 was a torture device with the stock tips. At the same time, it was one of the better sounding Stax headphones at any price, at least in the 003 version. Go figure...

Something I noticed the other day - Qobuz has tapped into Gramophone and a few others like 4F to add Editor's Choice and the like. Not that big of a deal, but a nice addition.
