Last week I finished assembling the Super Carbon, and it's now up and running. The first listening impressions are very encouraging, but there is still some audible background noise that needs to be eliminated. At the moment I suspect it's related to the power supply compensation, possibly an oscillation. On the schematic, around the STN0214, there is a 470pF/1kV capacitor. I initially installed a 5pF/1kV capacitor there, so it's possible the compensation at that node is simply insufficient. I'm currently waiting for some mica capacitors to arrive so I can experiment with the compensation network. While simulating the circuit in LTspice, I measured approximately 540V VCE across the STN0214. Based on that, I don't think the PBHV2160(VCEO = 600V) is an ideal substitute for the STN0214, especially if you're targeting output voltages significantly above 600V. On another note, I also performed the initial testing of the D&G 211 filament supplies, and they appear to be working as expected.- What are you listening to Part the Third

- World Cup Fever
I was rooting for France because I think Mbappe is a class act. Spain was the superior team, I mean only one goal scored on Spain the whole tournament? That’s crazy shit. I am definitely rooting for England tomorrow, for many reasons but a Mbappe vs Messi clash could be epic.morphsci started following World Cup Fever- World Cup Fever
Congrat to Espagne. Looking like the best team of the tournament.- World Cup Fever

Unfortunately, the dusty haze kept me from capturing the full moon. It's normal here ☹️ I had planned to go to one of the highest points on the island on thursday to try and take some pictures of the Milky Way... I have confidence in my equipment but not in my abilities. Some photos with the RF 35mm F1.4L usm. I really like how this thing catches the light.- The Official Head-Case Photography Thread.
BTW, where is our full moon?- HC Bike/Cycling Thread
I actually think Phil has been more coherent than he was a couple weeks years ago. He's on some good brain supplements or something. It will be a sad day when he hangs it up.- HC Bike/Cycling Thread
I think it might be time for NBC to retire Phil Liggett after this tour. Visma decision to race most of the "A" guys at the Giro looking catastrophic. Jonas gonna have to really battle for 2nd. His team is totally missing in action in these final GC bunches. I know Wout is missing, but the rest of the guys are not exactly helping their leader. Red Bull and Decathalon should be smelling blood right now.- The Official Head-Case Photography Thread.

CONFESSIONS II by Madonna (2026) https://open.qobuz.com/album/l00mdxqzi41sa Example: The Example gives you a smattering of what is on the album. (also a reminder, don't look at the sources of the green lasers). It is pretty much a Stuart Price joint. Dance music all around, mostly on the EDM side of the fence. Is there great singing? Na, Is there great lyrics? Na. Is there drops and beats and drops and beats? yup. Sounds good and I bopped along. And there are some colabs here and there.- RIP someone or another
