    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
