What are you listening to Part the Third
^ I have the original vinyl from '87. It was the first vinyl I had, a gift from my mother when I was just 10 years old and I released my first stereo. Over time I have been gathering different versions, both on cd and vinyl. I love that album and it means a lot to me (along with the "blood sugar sex magik" and the "seventh son of a seventh son")

CFAe runs hot, VERY hot. I would prefer a "normal" heatsink...

and now for something completely different part 3
Thanks. Although the GRLV is very clean and stable, for preamps I prefer to use R-cores and easier to place in a single chassis since they do not electromagnetically interfere (or very little) with anything. Itยดs optional so you can perfectly use a toroid Now that I've seen the preview, it's been a little over a year since Dr. Gilmore sent me a design for a new buffer based on the CFA architecture. At the moment I have not been able to put it into operation. If confinement and anti-virus measures allow it this year I could have it ready.

What Are You Building Today
Yesterday I received a Proxxon 28566 base for mini tool (I normally use a dremel 4000 and a Bosch GRO12v-35) ). I thought it was better than the Dremel base, in fact Proxxon uses better materials and has a reputation for making high quality mini tools, but I was disappointed. Although the materials are much better than the Dremel (Itยดs made of aluminum and steel and Dremel use plastic), the guides are "crooked", so that when lowering and raising the tool, it is locked in any position. I have tried unscrewing the guides, but have not gotten a proper tool movement. I'm going to see how to modify it. ๐

I usually use Modu boxes. They are expensive (I live outside the continent) but they do the job. That heatsink is overkill for a single CFA. Even for 2 CFA's they are still a bit oversized (BIAS 190mA). 24vDC power supply. Use OPA445.

Part Sourcing Assistance/Advice Thread
Besides, there are also companies that close or go bankrupt... I have several grains of sand from Semisouth designed for use in solar panels/conversors AC/DC (and later on amplifiers obviously ๐) that today cost a small fortune.

Add to the list all the sand related to high voltaje. Who said that silicon was expensive?

Get your game on!
It had been a long time since I played with another of my favorite flight simulators. IL 2 Sturmovik It's a shame it doesn't have a clickable cockpit like DCS World. I spend hours flying the "Flying Circus" on the Fokker DR I with t he von Richthofen's red skin.

RIP Sennheiser?
I really like using the HD800 with the Dynalo Bal ... I think it's a good combination
