I can't believe I'm going to bore you all about Newton. Although English, he wrote Principia and Optiks in Latin. An that is a real problem - translating back into English is a tickly thing, particularly the more fundamental stuff which is to do with what we learn as Newtons laws of motion at school. What is the precise translation of momentum for example? After that the translators have an easier job. Newton derived all his proofs in his long book Principia geometrically, step by step. He finishes off by meticulous measurements of the motion of the planets etc. At one stage he says that a chunk of the measurements was lost, but he can recall the basic idea behind the measurement. By "lost" he actually meant that his dog ate some of the sheets, or knocked a candle over and set fire to some sheets. Accounts vary. As professor at Cambridge University, his lecture course was so unpopular that no students attended. But part of his job was to give lectures. So he'd turn up and give the lecture to an empty theatre. In later life he spent most of his time studying alchemy. I'll shut up now

Another batch of chili. This one I'm talking to work tomorrow. This is my 7 qt. Dutch oven, so it's a big batch. If I haven't posted my recipe before: Dice two bell peppers (red & orange), and a medium yellow onion. Sauté in a lg. skillet. Set aside in 7 qt. Dutch oven. Brown 2 1/2 lbs. of ground beef in same skillet, salt and pepper to taste. Use slotted spoon to separate ground beef from rendered fat. Place ground beef in Dutch oven. In sauté pan add 16 Oz. can of diced tomatoes of choice, one jar of fire roasted salsa, small can of tomato paste, 16 Oz. Red wine, 1 tablespoon of Worcestershire sauce, tablespoon of minced garlic, spices ( I use Carroll Shelby's chili seasoning). Cook over medium heat until hot and well mixed. Add to Dutch oven, along with 1 can of pinto beans and 1 can of Black beans. Mix well and simmer covered for 15 to 20 minutes. If needed mix masa flour (included w/ chili seasoning) with 1/3 cup of water. Stir into chili, recover for additional 5 minutes. This will thicken the chili nicely.

So sorry Brent…. With my dad’s passing, some family and friends have been reflecting on mortality a bit. Many of us are experiencing that kind of thing, people our age up through parents’ age losing folks around them. One called it the worst curse of aging, and I can agree…. Wishing your mom and family the best!

^ Agreed and nice fall off. Visiting my dad and hit a nearby car show last weekend. And by car show I mean a car. Rain threatened the event so only a 1974 Challenger 383 Four Barrel was left when I showed hours before the scheduled end. Quick tests of the used Hassy 55v f/2.5 I recently picked up. Much to learn.

The Outlaws (Prime) - fun watch. We're through the first two seasons, looking forward the third.

I am working on a CFA3 build where the original THAT340 input devices have been changed to a JFET input pair. For a rough simulation I used these models: .model 2SJ103 PJF VTO=-1.5 BETA=10m LAMBDA=0.01 RD=20 RS=20 CGS=50p CGD=45p IS=10p .model 2SK246 NJF(Beta=2.5m Vto=-1.5 Is=1e-14 Cgd=4p Cgs=5p) This is only intended as an input-impedance / loading check, not a final device-accurate distortion simulation. With the current SS input/feedback network: R24/R26 = 5k R44/R49 = 50k C9/C10 = 20p I get approximately: SS mode input impedance: ~11.7k ohm per phase at 1 kHz ZF mode input impedance: ~50k ohm per phase at 1 kHz So even though the input devices are JFETs, the SS mode input impedance is still relatively low because of the surrounding SS input/feedback network. The practical concern is that I changed the volume control from 10k to 50k. With a 50k attenuator, the source impedance around mid attenuation can be much higher than with a 10k control. That seems like it can load/interact with the ~11.7k SS-mode input impedance, while ZF mode is much less affected. I am considering scaling the SS input/feedback network values upward while keeping the same approximate ratio and compensation time constant. Current: R24/R26 = 5k R44/R49 = 50k C9/C10 = 20p Conservative option: R24/R26 = 10k R44/R49 = 100k C9/C10 = 10p Simulation: SS input impedance rises to ~20.2k per phase SS gain changes from about 15.0 dB to 14.7 dB More aggressive option: R24/R26 = 15k R44/R49 = 150k C9/C10 = 6.8p Simulation: SS input impedance rises to ~26.6k per phase SS gain changes to about 14.5 dB The idea is to reduce the current drawn from the volume control and raise the effective SS-mode input impedance, without changing the low-frequency feedback/input ratio too much. Has anyone tried this on a JFET-input CFA3, especially with a 50k volume control? Does scaling R24/R26 and R44/R49 like this seem reasonable, or is there a known preferred value set for JFET-input builds?

Sorry to hear of your mom's losses Brent. RIP Bones

Sorry to see of your mother's partner's passing, Brent. Godspeed, Bones.... Sam

My condolences to you and your family, Brent. RIP Bones.

Condolences to you and your mother, Brent. She must be very sad and lonely. Life can be such a bitch…

You can't fool me, that isn't a woofer.

RIP Dale Jones, aka Bones, aka my mom's husband. He had been dealing with dementia and was moved to a nursing facility the day before. We knew it was coming but she has lost her brother, sister in law, a close cousin, and now Bones, all in the past few years. Not many people left in the family and it's tough for her.

Sam Neill RIP. Aged 78 BBC NewsSam Neill, Jurassic Park and Peaky Blinders actor, dies a...The New Zealand actor, who was born in Northern Ireland, died in Sydney. He had recovered from cancer and "the loss was sudden and unexpected", his family says.
