Very interesting thread. I looked at the circuit introduced. I felt nostalgia for the 2SC1815 and 2SA1015.
They like staple foods for us from the 1980s until around 2010. The 2SA1015 was surprisingly low noise and was used for Rx Preamp in the then hit CB Band Amplifire.
I hadn't used a parts with legs in years, so I wanted to build one. I wrote about it on my blog.
It is in Japanese, but I think it makes sense with machine translation.
