  1. What The Hell Happened to Head-Case?!?!? TLDR version: The datacenter that the head-case server is located in sustained a power outage on April 4. When the backup generator kicked on it caught fire and that lead to the fire suppression system (a fucking water based one!) kicking on and causing water damage to equipment. The head-case server was in the 'more affected' area of the datacenter and as such was offline until early in the morning on April 24. For further details on the incident you can see here: https://webnx.com/outage-updates/ You may be wondering why during such a long time the site wasn't simply migrated elsewhere, this is a fair question and the answer is simple. As this is a hobby site the backup process hadn't been properly verified as working in quite a while and the latest verified backup was nearly a year old. Migrating the site and loading it from that last verified backup would have meant losing a years worth of content. This was not a valid option and until I could confirm that the drives in the server were dead I wasn't willing to restore that old of a backup. From what I can tell there has been no data loss but I don't currently have a full report as to what if any hardware needed replacing to get the server back online. Due to that lack of info, I don't trust the server and I wouldn't be surprised if there's some additional downtime due to hardware issues. The Future A fresh backup at the time of this post has been taken and moved off-site. Over the next week or so a new backup process will be put in place and verified. After that is done it's very likely that the site will be moved to a new hosting provider. Further details about any move will be provided at the proper time.

  2. Here's a new twist on my T2 build. I've added both the HE-90 jack as well as a custom built Teflon HE-60 jack with appropriate voltages/resistances. This one is in black chrome That's the back of the power supply...

  9. I've always admired this group. The hobby and community got me through some rough times, even when I didn't say I was going through them, but just coming here and laughing my ass off at the shenanigans was enough to brighten up my day. It's been a while since I've been around, and life definitely throws some unexpected curve balls. I got married a month ago. I'm moving out of my apartment to a new home, where my wife is going to help me NOT turn the place into a man cave, but make it cozy and welcoming. I'm in love. When you know, you know, as the saying goes. Things change, people, change... I think I evolved leaps and bounds the past year in so many aspects. I've been packing for my upcoming move, two weeks away. Been having fun going through a lot of my audiophile gear that at some point I stored away and forgot about because another flavor of the month came about. I was remembering the meets, the trips to Cigar City in Tampa, Hunahpuh days, etc. Good times. I guess I just wanted to drop by and give thanks to everyone. Nostalgia hit hard. Fun times! Good stuff.

  10. Just before they pulled the patch off of my eye, they told me that more times than not, your vision won't be fully matured for about a week. Then they took off the patch and immediately tested my vision. Right out of the gate I could easily read the 20/20 line of the chart. I could read all but two of the letters on the 20/15 line. The Dr. told me that at my appointment next Thursday, she wouldn't be at all surprised if my vision was 20/15. She said that happens in about the top 10% of patients. I couldn't be happier. It's so nice to be able to see in stereo vision once again. It's been about 2 years since I've had any real vision out of my right eye. And my depth perception is fully back! I may need readers in a dark restaurant, but I'm typing and reading this now with no glasses on.😎

  11. Some more good progress. The amp is up and running I've got two issues on the board, but the amp, power supplies and USB-C PD / battery management are all working great. The wires going to the pot are temporary. There'll be a board for the analog/DAC inputs. The PD chips are small with lots of pins on them. I'm surprised I could solder them Lots of 0402 chips on the right side of the board... Here's the amp running with the battery (I need to have the input board done before I can put the batteries in the chassis). This is with the amp running and USB-C charger plugged in. Below, it is sending .18A to the batteries. The battery management will stop charging once the batteries are at about 12.5V. It drops the current as it gets closer to a full charge. With the charger plugged in and batteries fully charged, it doesn't draw any power from the batteries. At the moment, it negotiated 5V from the charger (source) and is boosting it to just above the battery voltage. If we wanted, we could source power so it could charge you phone too. I'll do a drawdown test tomorrow to see how long it will run on a charge. Overall, I'm very please with this amp. Kevin's amp design is fantastic. I've been listening to it for the last several hours with my SR-007's

  12. The curl only kind of shows up in this pic, but it is the best one I have. This is not, actually, ambrosia - it is from a tree that was tapped for syrup. It leaves the same streaking, but with larger holes (which I cut off). This was wood from the $2/bf scrap heap - same wood I made the kitchen counters from.

  18. After 5 years from the time I acquired the PCBs and parts, I finally took advantage of the free time created by the pandemic and completed my KGSSHV. This is the offboard version with +/-500V supply. I know many have since moved on to the Carbon but I am very happy with the results and plan on building myself a Carbon in the near future. Hopefully it won't take me that long this time. Thanks to Kevin for the great design, Spritzer for his support and providing some of the parts and this thread from which I learned a lot. The case is from Aliexpress but I got a new front panel made at the local machine shop.

  20. In other news, I just got back the analog input board and assembled the amp. The sandwich is 6.2mm thick + bottom components for a total of about 9mm thick. Batteries are about 10mm on top of the input board. Back plate on and plugged into USB-C (charging LED on) Why we did this... Portable music Just analog from my phone at the moment. DAC is up next PS The Weight is 12oz or 340g

  23. Dropped Peter off for his two-week Outward Bound trip, returned our shitty rental car and now sitting in the Delta lounge awaiting our flight to Atlanta which leaves in a little under 12 hours. I like this lounge because they let you mix your own cocktails. If Delta goes out of business next week, you will know why.

  29. Forgot to post this yesterday - had a good day doing old-school manual labor after spending a good part of Friday helping my neighbor clear a small maple tree that fell over in a wind storm Thursday. They're selling the house in 10 days and didn't want the tree or debris to cause any issues with the sale. So yesterday I set out splitting a bunch of it. It's funny. The older I get the more I enjoy manual labor. I hated splitting wood when I was younger. Then it was time for Lily and I to make a cake for Andrew's socially-distant, outdoor-5-months-late birthday party that we'll host today with 5 of his buddies. Vanilla tie-dyed cake (pic of that after slicing later today) with chocolate buttercream frosting. Outdoor theater screen and projector test complete. I picked up a cheap Onkyo receiver off CL and will use an old 5.1 Cambridge Soundworks system for the noise. Should be fun and the total investment was less than $200 which seems insane.

  32. Made trip #2 to empty a storage unit for my dad. Good and bad news: Bad - he needed my help, he has had 2 hip surgeries but now has an inner ear "thing" and needs a walker for balance. Was pretty tough to see, but he is quite the trooper Good - what I was cleaning out was about 24 boxes of LP's and acetates....I'll try and see what's there (some are pretty fucking dusty/dirty, and some of the older acetates have broken) Bad - Karen (who is up in our Maine condo, I'll join her Saturday) is gonna be pissed at all these boxes in our dining room Good - there may be a couple store owners or contacts interested in the lot Bad - the condition of many of these is not what I was hoping But, unit 578 is clear, and he won't have to spend $400 for the next lease/payment.....

  37. Well cheap compared to all the monster amps out there So correctly done, one would do the Uberamp2-Raal edition, which results in something really big,heavy and lot of heat. And a custom and large chassis, and a pile of $$$ This is a bit cheaper and easy enough for just about anyone to do. From the Ti Opa541 datasheet, showing paralled opamps good for at least 7 amps rms of output into anything including a dead short... Designed to be mounted directly to the heatsink, amp board right angle to the heatsink. All wires to the board directly soldered, 4 oz copper highly recommended. Power supplies are a minimum of 24V at 10 amps, like this, but more current not a bad thing. You need a pair of these! https://www.mouser.com/ProductDetail/MEAN-WELL/UHP-350-24?qs=YCa%2FAAYMW011AuZKubw9Sw%3D%3D So by the time you get done, about $400 in parts. Better than spending $4500 on an unknown made in croatia thing with inside pictures deliberately hidden. .02uf is a film cap, 10uf are mlcc caps, .1 ohm resistors are caddock https://www.mouser.com/ProductDetail/Caddock/MP930-010-1?qs=%2Fha2pyFaduhEz86YdyVUnzk8BCJOExJuzQrioCIidHi6TdsKxEEAVg%3D%3D raalopamp - CADCAM.ZIP

  40. Made our way up to Maine, last trip of the year before we close our condo down. My son and his girlfriend spent over a week up here. After COVID restrictions at school, and then not co-mingling once they got home, it was a great break for them. Time together/alone, very little to do. Was happy they got that time. Stopped at one of Maine's more famous lighthouses on the way up, Nubble. Merry Christmas to all who celebrate!

  42. Analog can be very frustrating. This week I finally took my second-hand AMG Viella TT to a dealer who also does setup work. It had never performed perfectly and typically the tonearm won't track and just slides across the entire record. The only way I could get it to play when I bought it three years ago was with a cheap moving magnet cartridge and that wasn't consistent. I gave up on it for a long time but tried to get it going again months ago only to be thwarted even worse. The distributor works with this guy who sets up a lot of tables so they recommended that I have him address the known issues, check out the table in general, and then dial everything in, assuming that is possible. He immediately found a potentially major problem with the tonearm, but then fixed it. After mounting my Airtight cartridge (that I told him I was worried had lost its stylus) and setting up the arm, he discovered an even bigger problem that forces the tonearm to shoot across the record that he cannot fix and doesn't even understand how it could be happening. He then discovered that not only my Airtight cartridge but also my Lyra cartridge were stylus-less. Fuck me. I think the Airtight was killed by my cleaning lady years ago on my VPI table. The Lyra stylus might have been lost when I was trying against the odds to get the table going more recently but I'm not sure it was even there at that time because it would not track the groove at all. Result? Bought a like-new used arm from the distributor and a used cartridge from the dealer. He showed me how jacked up the tonearm was, and I have never abused it and kept the cleaning lady away from this TT better than my last. So never buy anything from Stephane Prunet on audiogon because he had to know about the defects. I also bought cleaning fluid and fired up my Clearaudio Double Matrix cleaner. Now I'm going to listen to the beautiful, beautiful music...

  43. Got a little over halfway framing my latest project... A 7' tall x 20' long set of monkey bars for a 5 year old boy. It's a former client, and she requested me, and my company just told her to let me have the project. It's a bit small for them to mess with. Of course it's overbuilt and it's kind of a fun little project. I'll snap some pics when it's done.
