BA-302 data

[James Gessling]

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.

Thanks, Jim
