finished my cfa3 this week, thanks kevin gilmore for the desing and the support from the forum members.
running on +-30v with moderat bias, changed the gain resistors to 3.2k for lower gain.
needed some 3d printed parts so that all fit fine, a cfa3 in a quad 405 chase. no pot this time, i use a dac with volume control or a preamp.
after all amps i build i think the best solution for a 1 case build ist mounting the trafos outside in vertical position, absolut no magnetic hum inducted. i also added grain oriented metal band around the trafos inside the trafo cases.

I've discovered that I'm not getting weaker the older I get, but in fact quite a bit stronger.
Yesterday I lifted a $100 bag of groceries with one arm, like it was nothing. I couldn't do that in my twenties!
In the end, I decided on the F2.8... In recent months, I've used the 24-105 F4L much more than the 24-70 2.8L because of that extra telephoto reach, and I have to say it works very well except at sunset and indoors, where I struggled to take good photos without too much grain.
At those times, I missed the 24-70 F2.8L. That's why I ruled out the 70-200 F4 and broke the piggy bank to buy the F2.8. 🙂
Some more photos with the 24-105mm F4L
RIP to my aunt, Gladys "Goldie" Schultz, 87.
She was an amazing woman, very calm and logical, yet with a deep compassion and a wonderfully dry sense of humor (I was recently told she was a tiny bit on the spectrum, makes sense now). She was an early woman in tech, mother of 3 wonderful kids, and so much more. She will be missed....and my dad is now the last living person from that generation....
She now joins her husband, my Uncle Ron.
Can't see it. Imgur are still blocking content to those in the UK. All I see is a blue screen with "Content not viewable in your region" in it.
Yeah, I know I could stump up for a VPN account to get around that. But I'm darned if I'll kowtow to Imgur's fit of pique against UK citizens.
