  1. That’s the good thing about being addicted to audio projects you always have 50 spare op amps, Jfets, transistors, etc etc.. I think when the Toshiba 2sk170 went EOL I bought 200 🤣 I’m far from
  2. They were made from late 2002 to 2006 so assume somewhere in there
  3. Hey houston looks like the purifi evaluation board.. https://purifi-audio.com/eigentakt/eval1/ Another collaboration from BrunoPutzeys up there if not exceeds the Ncore class D’s In most areas.. PSU looks like one of the hypex smps modules
  4. Looks like an interesting build never actually heard an 807 what do you liken them to???
  5. Mate all power to you and I’m glad your found something that is of interest and finding enjoyment. if your enjoying it that’s all that matters I was just pointing out practical considerations for it that’s all! As pointed out above your looking at an DC output of around 1.4x above the AC input for the PSU, there’s slight loss from sag (lessor factor given the current draw) and voltage drops cross the rectifier but close enough to 1.4x
  6. Houston your relentless mate I don’t know where you get the time 😊
  7. Rank, I read back a few post so apologies if I’ve missed anything. I suppose the first question is is there a perceived problem with the current PSU? I get that people like to run external linear PSUs for various kit, but I’m just wondering if there is anything you’ve notice that’s compelling you to change the supply? Or you just want to tinker 😊 Trust me I get the want to tinker but it’s always good to start with an issue you want to resolve or at very least an understanding of how you are going to confirm it’s increased performance (outside our very unreliable ears).
