My radio shack 150 in one electronic project kit (cat
number 28-248, maybe 1976?) contains a part listed as
an "Integrated Circuit". Model number BA-302 is
listed and that's what's on the part. It's a 7 pin
inline package. The text mentions it to be a "ring of
three" amplifier.
I've been having quite a bit of fun working with this
kit, never had one as a kid, but this part has me a
bit baffled. Internet searches haven't turned up
anything useful. Anyone can help? I'd really
appreciate it.
I had the 150-in-1 as a kid (and still have it)... ISTR they put the
equivalent circuit either in the manual or on the cardboard face of
the kit... it's a simple 3-transistor amplifier, and I've never seen
anything like it in the wild, but perhaps it was used in FM radios of
the day?
