Hi all,
This is a real cool old School amplifier chip. Reminds me a bit of the BA306 chip used in the Science Fair electronic kits like the 150 in 1 kit, which I got for Christmas around 1978.
The advantage of these chips is the fact that they use the same matched transistors with good temperature stability. And also that they use only a small place on the PCB.
Later on, these were replaced by Operational Amplifiers such as the LM741.
Great circuit you got here !
Greetings
