In progress Amp design by me, power supply designs and circuit board layout by kerry, support by birgir +/-300 volt power supplies. complementary push pull all bipolar design with cmos style multiplying current mirror.

I couldn't stop listening to this yesterday I was using my SR-007's. It drives them very nicely. Very rich deep bass and good imaging / sound stage, which is usually where the 007's suffer without the proper amp. This was running this off of a bench supply at 11.1V and it was drawing .4A very consistently. The top board is the +/-300V supplies (with input EMI filtering) and the one below that is the bias supply set to 580V. Each amp section is 1" x 2" and each of the +/- PS sections are 1" x 1". Bias is a little wider.

Ping ponged up a set of Naval Aviator wings and broke in one of my SurfPreps.

Had a nice conversation with a neighbor. He's a bit hard to understand, but more than willing to sit and chat with me. He hung around telling me all about his day for better than 15 minutes.

Threw together a scrap wood shooting board for the 62. Did the whole Rob Cosman build with the tape to keep glue up from warping the mdf. Seemed to work well.

Pulled an all-nighter into an all-dayer after a full day yesterday. Decided to spin the black circles for a change of pace

After several redesigns during construction I ended up with a multi-use storage cart. Need to finish it off with some French cleats on each side and decide if I Arm-R-Seal it or just use Shellac like the MDF top. Decided it needed more bling so added some Zebrawood holders and Woodpecker stuffs.

Hi! i would like to share my work with you. I made an dynalo amp powered by grlv power supply and a pcm1794a/cm6631a dac. Everything is totaly made by me. I also designed the pcb nd ordered it from JLCPCB. Amp offset voltage stays at max +-1mV and it is totally silent. Case is DOUK AUDIO. pictures: https://drive.google.com/drive/folders/1a6cbGFpN6s5EadR8DA_lb21ZFwOwzK4R?usp=sharing

Set up my Rega in my son's room, on top of an Andover Audio Spinbase. But just picked up an ADL GT40a to listen via headphones, and do some vinyl rips. First up: Chameleonsvox, lead singer of my favorite band. Great 2 album live set on red and blue splatter vinyl, with bonus 7", CD's, poster, cards and more. Well-recorded too!

Apple galettes and a Sicilian style pizza that tastes better than it looks

Some interesting background / history before the autopsy. Lots of feels in the comments.

I know, originality score of zero but winter appears to be departing rather quickly so I got out this morning while it was snowing a bit. It sadly turned to rain before I was done and has been doing that steadily for the last two hours. Still, much fun was had.

I've tried every shortcut to making bb drawers, from pocket holes to dominos to biscuits. In the end, I found that an actual joint was both faster and more accurate than any of them. And more satisfying. And probably stronger.

LeverCraft coffee in Austin got hurt by the recent freeze and needs to raise money. As a result, they’re selling a fantastic coffee for significantly less than they normally would. Please consider buying some: https://levercraftcoffee.com/products/single-origin-colombia-las-perlitas

I applaud this thread!!! On point 1 that James made, I am very guilty of helping cause this issue. I have mixed comments on the GRHV across threads for Blue Hawaii BJT, Carbon, and a few others as well. Just to make sure that it is almost impossible for anyone to learn from what I did. 😁 On point 2, I have tested 2 alternatives to the C2M1000170D, and both appear to work fine. One of them is pretty new and usually in stock: https://www.mouser.com/ProductDetail/?qs=vHuUswq2%2Bsy%2BS7yfkaWaCA%3D%3D Item on left is the one that is in stock. Item to the right is the al

Smoked Mac and cheese with a side of brats

That's probably for the better, given how fowl-mouthed he is.

One of my wet dreams... Threshold 400s and SL10

A little bit of playing with some options/config on the bias supply and we got it down to 40mA draw on the batteries Might be able to do a bit better still. All in draw now is 260mA. We have some ideas on how to maybe bring this down a bit more.

Last night's show is up:

It's not far from the gay bathhouse in Berkeley, so if you were so inclined, you could get smoked meat and get your meat smoked in one convenient trip.

Sometimes I talk to myself also.

This amazing 13 y.o. pianist playing Mendelssohn. Remember her name

Soccer Mommy - color theory Don't let her silly stage name fool you. She is a talented young woman. I like this one a lot.

Happy birthday! I bought you one of these, I hope Amazon doesn't screw up the delivery.

I was dismissive of The Beach Boys and never got the hype...until I watched this video. god only knows content starts at 9:13

A broken clock is still correct twice a day 🙂 Really, if you did the initial alignment with a good square, there's no reason you wouldn't get it right on the first shot.

Stopped the cabinet project to complete the build and do the Ng 5 Cut Test for the Cross Cut Sled. Based on the accuracy with no adjustment, I am guessing I did it wrong or did not do a long enough 5th cut.

Yeah, this. Not that it's unexpected given the amps that you used to build back in the day.

Are you feeling the music? Jasmine Jams to Zakk Wylde's solo from Ozzy Osbourne's No More Tears... way too short: Scuttle Buttin' – Stevie Ray Vaughan:

Inconel is the real deal. I'm big on using it on seriously boosted cars' exhaust valves. Was good to me despite the mile long beatings. HS

I used to go to the one in Campbell all the time and the Sunnyvale one in a pinch. I knew a lot of folks in the Campbell area (used to live at the Upstart Crow coffeehouse there) and I'd run into some of them there sometimes. In fact, it was the last time I saw Lloyd (old member here) was there. I kinda dug the weird decor and the bargains on snacks and stuff that lined the checkout area. I really miss having a local electronics store (even Radio Shack was better than nothing) but there ya go.

As a person I've always liked Jude. I know I'm in the house that "disagreeing with Jude" built, but as far as headphone villains go he's pretty low on my list. That said, this interview is a little weak in the way of journalism.

Neat! Thanks for sharing. Unrelated: my girl Alyson (bassist extraordinaire) covered one of the more wack Mr. Bungle tunes (sounds very Secret Chiefs 3):

And few other videos on its creation. https://www.openculture.com/2021/02/the-beach-boys-brian-wilson-beatles-producer-george-martin-break-down-god-only-knows.html

It's probably not going anywhere. Various iterations were either unstable or too noisy. Circuit boards for the Raal experiment (code named "Bridgeport") have been ordered. I should know more about that in a few weeks. Also, there is some thought to doing a very small run of a 10 year anniversary version of the L2. The basic circuit would remain the same, but there are a few changes that should serve as an upgrade to the original.
