Tuesday sourdough za. Tried something new and baked it on the pellet smoker.

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.

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.

Congrat to Espagne. Looking like the best team of the tournament.

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.

Finally... I can't resist.
