Damn, and here I was thinking it was just another singer/songwriter with a uke. Wowzers, so glad I finally got around to listening to (and watching a little) this VIRTUOSO! Thank you! Virtuosity without abandoning musicality, my beloved. I was in Guitar Center today (selling guitars, didn't buy anything), and I was severely tempted by a Fender Fullerton Jazzmaster Ukelele. Oh well, maybe I'll get an Enya Moon 5-string Taimane Signature Ukelele after I make big Epstein Didn't Kill Himself Files Do Exist Bucks.

priority SINAD, nothing else matters

Speaking of expensive... Anyone remember Kai Wong? In earlier days of YouTube, he hosted a bunch of photography related videos on DigitalRevTV, out of Hong Kong. DRTV doesn't really exist anymore, but Kai maintains some degree of celebrity in the online photography world. He's got his own YouTube channel. I'm not subscribed and have never watched any of his videos (before today) but YT's algorithm has taken note that I have been consuming a fair amount of photography related material recently. (I've been doing a deep dive on TTArtisan glass, the OG Canon EF 15mm F/2.8 Fisheye -- more on that later -- and of course specific M42 mount lenses like different iterations of the Asahi Takumar 50mm F/1.4. I learned that my non-multicoated 7 element version is probably radioactive.) I guess that explains the giant orange hexagon, but I digress... Well, ol' Kai managed to get his hands on a vintage French-made cinema lens, the Som Berthiot Flor 55mm F/1.5. I don't know a thing about the Flor 55mm or Som Berthiot in general. I do know that cinema lenses tend to be several orders of magnitude more rare and expensive than ones designed for still frame. They were made in comparatively infinitesimal numbers and only a small fraction were sold to the general public. Additionally because motion picture cameras feed the film through vertically, many cinema lenses don't make an image circle sufficiently large to cover the 35mm film plane on a still camera. The Flor is one such lens and it can be adapted to fit Leica rangefinder bodies. Consequently a clean example goes for upwards of 60,000 British Pounds in the rare event where one comes up for sale. I'm not necessarily suggesting anyone watch (most) of this video. In spite of Kai's best efforts with his little handheld wireless mic, the sound quality is lacking. Add to that the rather thick accents of most of the subjects and it can be a challenge to figure out what they're talking about. The example shots taken with the Flor are ...fine, but nothing dazzling. I own a (not so) small army of manual focus primes. While none of them match the Flor's specific unsharpness and color transmission, I can get to an equally interesting optical space with fair number of my vintage lenses. I can't mount any of them to Leica body, however. (Which is mostly fine with me, I have never coveted a Lecia digital body, but I would certainly give an M6 with a 35mm Summicron a go.) I'll go a step further and say that if there was lens that offered identical optical performance to the Flor, but was made in much larger quantity by a less storied maker (Yashica, for example) it would sell for maybe $100 on eBay.

This shit is pretty dire but I expect it got glowing reviews all over the place...

Yes, it's pricy. My eye is on the Fujifilm X-T50 but the phone will do for now.

I showed three samples, one of the demonstrated ones, the device defines as IGBT. I assumed that I was not the only one who encountered fakes...

I always do, but at that price it would be a different model.

topping dx5ii schematic class B output stage. and they seem to be proud of this crap. discuss dx5ii.PDF

Reassuringly expensive, surely?

at first... hmmm interesting. {internets check} hmmm ... pricy 🥺

You don't need another Camera, right @blessingx?

Peacock might want to think their ad copy, assuming it's not AI Slop.

Yet another Ric's rant: But why bother?

Ooof! A bit rich for my blood lol. My copy is below: https://www.discogs.com/release/11978254-Clipse-Lord-Willin (which I thought was quite fancy, apparently not enough haha)

Nice! I approve of your taste in Virginia-based "former" cocaine dealing rapping duos. Also, do you know about this? 7" 45 box set of Lord Willin'. Only 1000 copies made. I linked it to my buddy who turned me on to Clipse from like, day 1, and he wound up buying it, not realizing that I sent him the link I was going to buy it from. I got it elsewhere, but glad it wasn't as much as the ebay listing https://www.ebay.com/itm/276301100974?chn=ps&mkevt=1&mkcid=28&google_free_listing_action=view_item&gQT=1 Also, can you imagine dropping this 45 whenever you want? https://www.instagram.com/reel/DLhu9gosH0D/

You haven’t answered my question how you determined that the part is a fake (other than from the appearance).

Yeah I’ve been listening to the clipse non stop. Was a fan of their first album and followed Pusha T on his solo stuff

Sure, could be but there seems to be something going on as one user was apologizing to Stax saying "this fixed the issues he was having" according to google translate. For me the fit is pretty bad and the 007Mk1 pads made it even worse.

Maybe they designed it that way from the very beginning, thinking people would figure it out on their own. And then, after many years, they suddenly realized that no one actually knew why they made the earcups rotate.

LOVE this group, and they're finally back together after a decade and change break. They dropped a brilliant Tiny Desk Concert; I may need to watch it again.

If you use them in a constant current source, the Vbe-Ic curve (figure 10) is probably more important than hFE. If you don’t have ways to measure, pick two that are closest in hFE for each channel and hopefully they come close in other parameters as well. If you ask me, I always order at least 2x more than the BOM qty and match them on a curve tracer at or near the actual operating point. The bigger the pool, the more likely you’ll end up with well matched pairs.

In the batch that MOUSER sent me, the measurements were made at normal room temperature. One row of transistors had hFE 341, another - 315, the third - 295 and the fourth - 245. Which hFE would you use first?

If I were to choose from a well executed raster image logo in the marking and a badly burned vector one, I’d opt for the latter in a heartbeat. I’ve explained the reason and would not repeat here. For the hFE, you need to know the Ic and Vce your testing was performed at, in order to make a meaningful comparison with the numbers in the datasheet. If you don’t know, measure them. The datasheet says minimum hFE is 170 at 25 degree C, Ic=-1ma and Vce=-5V. From the chart you can see hFE goes slightly up from Ic=-1ma to -10ma and then to -20ma before it starts to drop after Ic=100ma (the red line). If your sample tests at hFE=150 between Ic=-1ma and -10ma, it’s below spec and would be a reject by the factory. You can see the red line is well above 200 and approaching the 300 line, so 340 is not a surprise. +/-20% is considered normal variation. Why would they specify min hFE at only 120 at Ic=-20ma? It could be a simple mistake, or indicating that the hFE could drop as early as Ic=-20ma, unlike what the typical curve suggests, which is a bad news for circuit designers (not applicable for our applications). Nevertheless, sandbagging would not get them into trouble anyways, if you know what I mean. I could go on and on and brag about my affiliation with the semiconductor industry, but let’s keep the personal information out of this discussion. If you think my comments make sense, think about it. Otherwise, just take it with a grain of salt.

when I bought in 2023 in Digi c2m1000170, they wrote that it was made in China. Now they don't have this model. I made a purchase on Aliexpress, alas, a fake arrived. I tried to make a purchase from another seller on Ali..., and to my surprise, transistors suitable for use arrived. I have already demonstrated photos of three purchases.
