  1. And now what did you do TODAY?

    Played a game of chess with https://en.m.wikipedia.org/wiki/Odysseus'_Gambit I hadn't played in 6 years but he lured me in and I couldn't say no. Obviously i got destroyed, only took down a bishop, rook and a couples pawns before getting rekt. Fascinating to hear him talk about his story
  2. Technical Assistance/Advice Thread

    Did you make a chassis ground on the amp, tie that to amp star ground and psu star ground which is connected to psu chassis ground? Edit: wow this is a great pic
  3. goldenreference low voltage power supply

    Okay I solved the problem by adding a DC heater supply, new dimensions 51x90mm
  4. goldenreference low voltage power supply

    I needed a medium voltage single supply GRHV, not sure if that already exists but if it didn't it does now. Some day I will get better at layout :/ Kerry could have made this half the size. 50x91mm, just 3 vias in total so I'll claim that was my intention all along as to why the board is so big but I'll take any suggestions how to shrink it

    Stay safe, Brent. You may identify with being white but these white supremacist shitbags are even getting DNA tests, which ironically prove that they are not as white as they think they are.

    @MexicanDragon what has it been like for you these past few days? Can't imagine good things with articles like this: http://www.knoxnews.com/story/news/politics/2017/08/16/tennessee-lawmaker-facebook-post-robert-e-lees-battle-flag-symbol-freedom/574774001/

    When do we get to read some of your lyricism?

    Some Tibetan yogi or other from a thousand years ago: https://en.wikipedia.org/wiki/Milarepa I've been trying to get back into poetry a bit, being reminded of Yeats' famous poem The Second Coming these past few days... any recs?
  9. Trilogy H1 electrostatic amp

    I think I see zener strings and the transistors on the tiny heatsinks might be pass FETs with protection diodes on the bottom

    “All worldly pursuits have but one unavoidable and inevitable end, which is sorrow; acquisitions end in dispersion; buildings in destruction; meetings in separation; births in death.”
  11. Trilogy H1 electrostatic amp

    You're not getting the point. Yes, everything can be "true" if you assume it to be true. You're simply assuming it's a cascode and then using a cascode calculator to get all your numbers. I found the schematic you're referring to in the Birt article you sent (thanks), and it's a totally different circuit from the SRX. This actually is a cascode, with some interesting voltage divider grid biasing action. Notice how it is a common cathode into a common base. I will try to simulate this in spice as well when I get the chance. birt schem.pdf
  12. Trilogy H1 electrostatic amp

    I just spent awhile trying to find the article, can't find it so clearly it is a very popular and well-regarded article in textbooks and circuits today. This is fun, I love playing devil's advocate even though it is clearly not a cascode. What do you think the open loop gain and output impedance of the front end of the SRX is, disregarding and with Miller capacitance? I'm going to put it into spice and do a comparison with a real cascode.
  13. Trilogy H1 electrostatic amp

    The definition of a cascode is a common emitter into a common base (or the tube equivalent), please tell me where you find that in the SRX. srx schem.pdf
  14. Trilogy H1 electrostatic amp

    Couldn't the input tubes be cascoded like the T2 instead of the Srx's LTP into a common cathode with the plate/cathode resistor doing double duty?
  15. And now what did you do TODAY?

    So sorry to hear, condolences to you and your family
