  1. Today
  2. Quick update: it’s 6 AM here in California and I just wrapped up some late-night tweaking. Someone PM’d me earlier asking how I solved the offset and balance issue, and I can finally say: done. Offset is now around 0.3V and balance is about 0.2V. If anyone else is running into similar issues, here’s what worked for me: 1.CCS Set Resistor: I kept the CCS set resistor at 1.5k, which gives around 22–23mA static current. You can try lowering to 1k if you want around 25mA, but I found 1.5k sufficient. The more plate current you have, the higher the offset you will get. 2.Cathode Resistor: Changed from 3300Ω to 7k–7.5k. A larger cathode resistor gives you a deeper grid voltage. I could only find suitable 7k wirewound resistors on Mouser – they’re a bit bulky but still fit. Note: Larger values will increase the offset, so some trial and error is expected. 3. Grid Pot: I replaced the 10k pot with a 50k, which gave me a much wider range to trim both offset and balance. Final bias: around 24–25mA static current, Vgk ≈ -75V. Hopefully, this helps anyone else dialing in the Megatron XL and happy tweaking!😊

  5. The original is on the right... the left one is clearly a fake
  6. sorry, I have one 100% original and 10 fakes, many do not know who the original is.
  7. 2sa1968 is in fact a PNP 900v. 2sc1968 is a 500mhz rf amplifier.
  8. When I was looking for 2SA1968, I also got PNP. I couldn't make a claim to the seller, because according to the Toshiba datasheet, there is such a version too. Model 1968, one for the whole world, n-p-n and p-n-p

  10. Arctic Monkeys - AM vinyl Forgot that I had this record. Not a bad song on it. Qobuz - 3 songs in. Enjoying so far.

    This is the 12th eruption and we have reached the point where people are protesting unfair police closures. It's well away from anything and already fizzling out so nobody is worried.
  12. Not really any new news, but Sunshine was mentioned in the NYTimes today https://www.nytimes.com/2025/07/17/us/maine-arrest-paddleboarder-homicide.html?unlocked_article_code=1.XU8.U18S.PmIKYhI8LmAu&smid=nytcore-ios-share&referringSource=articleShare (Gift article)

  15. Horrible story indeed. Glad the perp will at least face trial.
  16. Stax have been having issues with fit, so it's not surprising. The new Lambdas never fit on my head properly and the yokes needed modding. The Mk2 versions improved things, but not enough. They're obviously not testing their stuff on a wide enough range of heads. At least the Lambdas with their cheap construction are easy enough to mod with 3d printed parts. The X1 fits very nicely, however, but I could use more steps in headband height adjustment. To be fair, the original 007 was also not perfect with the fit, as the self-adjusting headband was too tight, but that could also be modded. So, business as usual?
  17. Dear lord. Today's news is insane, and leaves me with more questions than answers. Sunny was a tough woman. Not superhuman, but definitely world wise and not easily intimidated. She grew up in a harsh environment and knew how to fend for and defend herself. There's some missing piece of this story we still don't know. Is this kid a physical giant? Did she know him? I suspect she did. Did he manage to sneak up on her? This would be an insane story in any location, but in a quiet town of ~2000, it boggles the mind.

  20. I can not make myself to read this shit not interested. What is strange it is the third bullshitter in a short time perhaps from the same source.
  21. wow, you take off 2 hours to watch a movie and then all of this. if that class B output section could actually deliver 1 amp or more that is required for just about every single planar or ribbon then maybe it might actually perform correctly. but the opamp cannot possibly supply enough current to drive the output stage. all the feedback in the world won't help. and for real world loads R2 actually makes it worse. multiple feedback loops and it looks just like the squarewave of the nfca module. more like a stair step. something the AP cannot possibly measure. hint: look at the quad current dumper. class B output section. performs well within its power limit. all this to reduce the current capabilities of the power supply. all this to reduce the heat generated because the heatsinks are way to small. yes its a piece of unreliable garbage.
  22. Thank you for making my day less boring and answering my question. I will label you as a troll and a psychopath.
  23. You must feel so clever after writing that long, dishonest, and manipulative wall of text. It's the most cowardly and hypocritical thing I've ever read. Let me make this painfully simple for your confused brain, so you can see exactly who I was replying to: When I mocked the irresponsible 'crap' comment, I was talking to KEVIN GILMORE. When I despised the 'only warning' threat, I was talking to CRAIG SAWYERS. When I slammed the coward who hides behind others and calls for backup, I was still talking to CRAIG SAWYERS. Do you get it now? And you, jamesmking, jumped in every single time like a dog whose tail has been stepped on, desperately defending all of them while crying 'It wasn't me! It wasn't me!'. You are not an independent debater. You are their HUMAN SHIELD and their designated CLEANUP CREW! Your only purpose is to follow them around and try to polish the turds they leave behind. And you're 'saddened'? Oh, please. Don't you dare lecture me on 'respect' and 'the grey between the extremes' when you end your little sermon by calling me a 'psychopath'. Your line about 'I haven't reported you (this is NOT a threat)' is as sincere as the rest of your nauseating hypocrisy. You are not a debater. You're not even a competent coward. You are the most pathetic kind of apologist machine, completely devoid of independent thought, attached to your friends' coattails. So take your sanctimonious pity and shove it. Your 'journey' is nothing but a muddy path of you rolling around in the filth your masters leave behind.
  24. for me that's the entire heart of the matter. I want maximum pleasure from music and if the devices giving me maximum pleasure don't measure fantastically I don't care. If they do measure well that's fine by me too. That's my hearing and that's what I optimise my hifi for.
