We lost power for about 12 hours which is nothing, all things considered, and we've got the generator/transfer-switch so it was really only out for 4 hours because I didn't feel like setting it all up at 2:30am when it went out. Still, a freak storm. I went to bed at 11pm and at that point we had maybe 2-3" of snow. Got up a little after 6 to start cleaning the driveway and setup temp power. We had 16"+ at that point and it was still coming down. I finally made it into work at 11am, where we were running on self-generated power. Some lines not far outside the base came down and landed on rail road lines and made for quite the lightning show for the local residents. Everything is pretty much back to normal around us at this point but there will be significant yard cleanup as the trees in the front yard took it on the chin again. Lily and I made the best of it yesterday afternoon and went out for about a mile and a half snow shoe in the woods.6 points

While I cannot speak to the rest of New England, having spent winters in Minnesota, Wisconsin, and upstate NY, I can say that people in Connecticut* cannot handle their weather.4 points

Milo (Al's alter ego) and I did some work on our router table/mortising machine today. It's starting to come together... Milo did a huge chunk of the milling and drilling on this, and all the holes and pivot points lined up perfectly! Of course, he stacked the deck a little bit... So upright, it's a regular router table, albeit a large one. tipped down, it's a mortising machine, or horizontal router table, useful for things like raised panels and such. We're really having fun building this and setting up shop in general. Still left to do... cutting the hole in the table top for the router lift, and painting/sealing.3 points

Thanks all! We aren't as bad off as others, it's easy to keep things in perspective. At the hotel now, after a warm and comfy night's sleep. We found my mother-in-law's place has power, and I believe our place does too now; we'll check after we leave the hotel. Cleanup and replacing food are the next tasks. But everyone is OK, that's the best thing. Wishing good thoughts for others! Sent from my iPad using Tapatalk HD2 points

Went to my first sugar shack. Ate so much. They start out by giving you a doggie bag to fill as you go. I'm not going to even try and describe everything, as I'm not really sure, and most of the descriptions were in French. Lots and lots of foie gras and maple syrup. I nearly died.1 point

Went to see Run The Jewels And Lorde 10th row center is a solid spot it seems. Sent from my ONEPLUS A3000 using Tapatalk1 point

If you want inability to cope with snow, the south of England takes the prize. It can be many years between proper snowfalls, so it's cheaper to just grind to a halt occasionally than build infrastructure to cope. This is almost literally true:1 point

Will give it a listen! Thanks. EDIT: No, definitely not too derivative, melikey this big time.1 point

because i'm lazy, taobao links for liquid gold clone and LL please. approximate schematic here. too lazy to finish the plate servo. some resistor values obviously wrong, probing from here with voltmeter to Iceland seems unreliable. (and kinda slow) .1% thd at 10khz 2nd harmonic. which is not that horrible cth2.PDF1 point

I haven't spent any time comparing them but this R2R seems to be a very different animal. It also goes through the main amp all the time as the gain switch is active even in fixed output mode.1 point

I'm totally diggin' the new TNT show "The Alienist". It hits all the complicated characters buttons. The sets are amazing and right up there with big budget movies like the Robert Downy Jr Holmes series. Great "Nerds in Victorian New York" fair.1 point

Call from mom because dad clicked the receiver onto an input other than cable. I tell her to push the button on the front labeled "Cable". Her response "it's dark in here I can't read the buttons".. Me " turn on the lights?"1 point

Mini Dynalo After running the amp for over an hour, bias was 14+mA, so right where I want it to be. I thought it might be interesting to create a table or spreadsheet showing different users biasing and results, so I made a Google sheet, here: https://docs.google.com/spreadsheets/d/1D5LDuRdupZRoWR-GfAd03fkFSBAMY4-E_VcYfCAI1Z0/edit?usp=sharing Go ahead and fill in your info if you like so this is available for all to see. Note: this is the first time I've created a Google sheet, so let me know if you can't edit it and I'll try to figure it out Heatsinks: I've been looking for some. The ones that @mypasswordis mentioned from ebay don't seem to be available any more, and I'm having a hard time finding any that appear to be suitable size. There are some I almost pulled the trigger on that were 50mm x 25mm, but the 25mm would leave the end transistors half covered. I could get the Fischer SK81/37.5/SA from TME and cut them in half, but I'm trying to avoid that if possible. I'd need enough for 3 amps. EDIT: Found these, 45 x 35 x 18mm on ebay https://www.ebay.com/itm/263051780518?var=5620541922001 point

I’ve used a couple of different offset servos with a Blue Hawaii. I found them very useful. If you like 45 volts drift you should avoid all kind of servos.1 point

Success! After a few days of dealing with the regulators I finally got them soldered in properly. +V: 20.00V, -V: -20.02V of course the 0.02V offset is super annoying even if it is within 0.1%. I calculated that I would need to add a 23.8 Mohm resistor in the AOT spot to adjust the voltage to -20.00V. Not really worth it, although I might just add it to my next Mouser order.1 point

Ehhh who hit you with the stupid stick? I've lost count of how many tube amps I've designed so I'm well aware what tubes can and indeed can't do. Nothing to do with my amps either, some of my customers have Lampi dac's which is why I know they are such utter shit. Now, since you know so much about tubes...are tubes less noisy than transistors? Are they better at amplifying low level signal than transistors? Are they superior in terms of distortion and other artifacts that deviate from the original signal? Nope, fuck no and hell no respectively. What you fail to grasp is how tubes are used and where they work the best. That sure as shit isn't a tube output stage of a DAC which is ironically fed by a current output dac. Also since you bring up the T2, I'm well aware of it and I'm even revising the circuit boards now to hopefully increase its performance so let's dwell on it for a bit. Is the T2 the best amp there is for electrostatics...nope, it isn't. Would it be better if you replaced the front end tubes with fets and the output tubes with SiCfets? Yup...by quite a bit actually. That has nothing to do with "tube magic" or other such BS claims based on not having the slightest grasp of what is going on. The fet's are simply better devices, made to much stricter quality standards. What tubes do well is simple circuits, even silly simple sometimes and they are forgiving of "designers" who don't know what they are doing. It's hard to blow up a tube...though some people have tried their best to do so. Ohhh and they were excellent for HV output duty but the SiC fets are clearly better. As for these super qualities which are now just coming to light...is there anything to back up those claims or just your own BS? I take it the GG is still using a Soekris dac fed by an off the shelf PSU from ebay and another ebay special USB input. Well shit...I have all those parts...hell even two Soekris boards so I should throw something together and charge somebody 40K$ for it. I have some DHT's too so let's make it super exclusive and throw a tube output stage that does fuckall but looks super cool...ohh and fuckups the sound for good measure.1 point

Options are limited; 1) Use a permanent epoxy/glue and risk not being able to access parts again. 2) Use non permanent tape/glue and risk the heatsink becoming loose and shorting something. 3) Let em run hot. I’ve adopted option 3, have measured ~74°C, with an ambient of 24°C after an hour fully cased. Not ideal, but not catastrophic and well within running spec.1 point

Kerrys awesome mini will fit a FPE profile 1 enclosure. The smallest I could get it: 133.92mm (W) x 172.72mm (D) x 42mm (H) Smaller than Cavalli’s Liquid Carbon in height and depth, and only slightly wider by 6mm. Cavalli’s Liquid Carbon = 127mm (W) x 178mm (D) x 45mm (H) I get my panels next week, I can’t wait to see how it turns out! Here are the drawings. Will share if anyone’s interested .1 point
