Thanksgiving dinner included.............sweet potato biscuits Paging Brent.....5 points

Lots. Thanksgiving with some non HC friends. Deep fried Turkey, from an electric SV like device 12lb bird cooked in 48 minutes, so very un-sv like Sides included brussel sprouts with bacon Yum ( two types of potatoes, two stuffings etc) And then there was dessert So of course, I had to try a bit of everything. Happy Thanksgiving head-case, to you and your loved ones.4 points

I don’t have to listen to it to know it sucks. iSquirrel is useless, ignorant of even the slightest clue as to anything technical, his profile fits MSB marketing perfectly. “Quite frankly I don't care what's inside, only what it sounds like.” iSquirrel November 2016 Says it all.4 points

single sided even, can add a ground plane on top if necessary, current size 3.45 x 3.7 inches, i'm sure birgir will be able to shrink it in the one direction you need 2 per channel, stack on top of each other, or next to each other. I should probably add some mounting holes.3 points

First time making the family secret recipe cheesecake in FL. Turned out perfect but the best part is Peter is learning how to make it so the recipe will be carried on.3 points

so sorenb really wanted this, so here it is http://gilmore.chem.northwestern.edu/cfaelectrostat.pdf the outputs are 300v darlington transistors just need to find a suitable npn match for the stn9360, and this can be done all surface mount tiny, fully complementary, fully dc coupled, decent input impedance (none of this 75 ohm nonsense) push pull output... edit: PBHV2160ZX looks great for the npn. so you can add one more set of outputs and run up to 500v power supplies balanced input only, and you need 4 of them2 points

That is the dumbest thing you have ever posted here, not that there hasn't been some legitimate competition.2 points

I was collecting books on electronics, how electricty, especially electrostatic, works etc. Mainly old university lecture books... I bought a book recently. I thought it was just an old lecture book. But turns out it is a extremely rare book published in 1939, and only 2000 coppies printed. And mines condition is really good for its age. It was written by Prof. Dr. Georges Bruhat and translated from French to Turkish (well ottoman language; some kind of blend with Turkish, Arabic and Farsi) It has good basic info about electricty. Hard to understand cuz of its language, but still...1 point

for V+: (R8 + R7) / R7 x 10 (reference voltage of D5 - LT1021-10), R7 = 1.5K, R8 = 750 for + 15VDC for V-: (R9 + R10) / R10 x 10 (reference voltage of D7 - LT1021-10), R10 = 1.5K, R9 = 750 for -15VDC On the goldenreference4 board silkscreen, R7, R8, R9 R10 are all 1.5K. R7 and R8 are connected and R9 and R10 are connected. R8 and R9 are the 1.5K resistors closer to the DN2540 on each side of the board.1 point

The what now ? Don't really care for a newb trying to suggest 'manners' like you know us when you haven't even seen us at our worst . Just settle in and read for a while , I'm pretty sure all forums would appreciate that . Is head-fi down again ?1 point

I that might be just be correct. As for those "reviewers", they are pretty much why the market is so fucked up. Why people like Single Power, RSA, Cavalli, ALO, DNA, Woo, Wells, etc. etc. continue to operate. "How I feel" with no real basis for comparison rules the roost. Ohh and "I own expensive shit" actually means something to these people when it is meaningless as anything. Anybody can buy expensive shit, doesn't mean you know anything about it.1 point

Ahhh, yet another high end snob who couldn't afford to buy a clue. Buy anything with a high enough pricetag to continue that lie that he knows anything. Utterly pathetic.1 point

I think you all will really like this one, a current feedback fully dc coupled fully complementary electrostatic push pull amplifier. what the msb could have been if they had decent engineers. just need to find a match for the stn9360 http://gilmore.chem.northwestern.edu/cfaelectrostat.pdf1 point

anyone that has ever listened to the koss esp950 will agree its clinical and cold. it tests pretty well, thanks to gobs of feedback. but lets look at the msb specs a bit Dynamic Range >140 dB Frequency Response 0Hz-20Khz, ±0.8dB XLR Input 75 Ohm Balanced 4Vrms Maximum Common Mode Rejection Ratio > 120dB CMRR @ 60Hz > 90dB CMRR @ 1kHz > 70dB CMRR @ 20kHz Crosstalk > 90dB Crosstalk @ 1kH > 65dB Crosstalk @ 20kHz now its obviously transformer input based, so 0 hz implying dc coupled. flat out lie. and its already down by almost 1db at 20khz meaning that its slew rate limited and likely this is into no load, once you add 120pf, its going to be worse. 75 ohm input definitely implies that transformer. that dynamic range number is at least 30db off. and where is the distortion specs. Likely the distortion specs are much worse because I don't see any opamps with piles of feedback. stupid massively overpriced crap.1 point

looking at the picture blown up. 450V, 330uf and if you look, 10 transistors, all in series, banks of 5. and lots of resistors to balance them all. (sot223-4 transistors) sure looks to be a bipolar version of the koss esp950. so its a voltage stacker. transistors are likely matched pnp and npn, and are rated for 250 to 300v (5 transistors with 900v total power supply) there are no power output transistors attached to the heatsinks input transformers are used as the phase splitters IF (more like when) it blows up, its impossible to repair.1 point
