Thanks for the answer😊. I just placed the order.

Circuitdiy told me they had no more pairs.

Yes, thanks Nelson!

I've read the article 4 times now, I think... It's like peeling an onion, every time I learn something more... It's so much information.
Thanks Mr. Pass!
This is no starters Amp... So much layers to peel....

Thanks Nelson! I like that there is a something new to learn in every atricle like I never experimented with cascode feedback etc and that is nice. The other part is not very interesting to many people beacuse you just can`t buy this parts. Almost all transistors are hard to get. The SITransistors are now days fake or very expensive, and if you have to match the pairs...the "fun" never stops, 2SK/2SJ mosfets are obsolete too...

I guess out of your reaction, that you think is too complex. I think you`re wrong, there are a different types of complexity, this is in fact very simple circuit, the coplexity is "vertical" ,as I would say, so try to read it

I am sure this refined front end and a BA-2 like output stage, may be also cascoded, will
give the Burning Amps new fire......! Even with Feedback!

It's true that the front end and output stage are independent of each other,
and this front end has general utility.

You could easily use the output stage like a follower amp with only minor
adjustment for higher input impedance.

No that's a gross misinterpretation. "Mind Blown" is a popular meme in the U.S. It's like "Wow!" times 100.
